| 13 | +When a _GitHub Actions workflow_ that had been working fine for months suddenly failed, I went down a familiar rabbit hole of false assumptions, vague errors, and misleading logs. This post details the troubleshooting journey, the kind that initially screams ***“runner environment change,”*** but ends in a quiet whisper: ***“your token expired.”*** |
| 14 | + |
| 15 | +## Context: Automation That Moved 🐛 Issues |
| 16 | +For context, I had a GitHub Actions workflow using `gh` (GitHub CLI) to automatically move issues labeled `bug` into a "Bugs" column on my GitHub Project board (#6). This workflow ran fine for months—until mid-April 2025, when it silently failed. |
| 17 | + |
| 18 | + |
| 19 | + |
| 20 | +- **Workflow Name:** `🐛 Auto Bug Column Management` |
| 21 | +- **Purpose:** Move issues labeled `bug` to a "Bugs" column in GitHub Projects (Project #6) |
| 22 | +- **Tools:** GitHub Actions, `gh` CLI, shell scripting, PAT-based auth |
| 23 | +- **Initial State:** Everything worked smoothly until mid-April 2025 |
| 24 | + |
| 25 | +--- |
| 26 | + |
| 27 | +## Initial Suspect: A Changing Environment |
| 28 | + |
| 29 | +Like many others, I use `ubuntu-latest` for my GitHub Actions runners for convenience. Around the time my workflow failed (mid-to-late April 2025), I noticed warnings appearing in my Actions logs about `ubuntu-latest` preparing to point to the new `ubuntu-24.04` LTS, updating from `ubuntu-22.04`. |
| 30 | + |
| 31 | +{{< screenshot src="ubuntu-latest-warning.png" alt="GitHub Actions warning about ubuntu-latest" >}} |
| 32 | + |
| 33 | +This seemed like the obvious culprit. Runner environment changes are a common source of workflow failures. I also checked the runner image software lists (like those tracked in actions/runner-images issues, e.g., #10636) and noted potential differences in pre-installed software, including the gh CLI version itself (my local gh 2.68.1 vs. runner versions potentially being 2.69.0 or 2.70.0). |
| 34 | + |
| 35 | +My first logical step was to eliminate this variable. I updated my workflow YAML: |
| 36 | + |
| 37 | +```YAML |
| 38 | +jobs: |
| 39 | + move_bug_issues: |
| 40 | + # ... |
| 41 | + # runs-on: ubuntu-latest # Changed from this |
| 42 | + runs-on: ubuntu-22.04 # To this |
| 43 | + # ... |
| 44 | +``` |
| 45 | +I reran the workflow, confident this would likely resolve the issue. |
| 46 | + |
| 47 | +## Hitting a Wall: The Cryptic Error |
| 48 | + |
| 49 | +Pinning the runner to `ubuntu-22.04` didn't fix it. The workflow failed again, specifically at the step designed to find the project item ID associated with the labeled issue: |
| 50 | + |
| 51 | +```YAML |
| 52 | +- name: Retrieve Project Item |
| 53 | + id: get-item |
| 54 | + run: | |
| 55 | + ITEM_ID=$( |
| 56 | + gh project item-list "6" \ # Project Number 6 |
| 57 | + --owner "socrabytes" \ # My username |
| 58 | + --limit 100 \ |
| 59 | + --format json \ |
| 60 | + --jq ".items[] | select(.content.number == $ISSUE_NUMBER) | .id" |
| 61 | + ) |
| 62 | + # ... rest of script ... |
| 63 | + env: |
| 64 | + GH_TOKEN: ${{ secrets.PROJECT_TOKEN }} |
| 65 | + OWNER: "socrabytes" |
| 66 | + ISSUE_NUMBER: ${{ github.event.issue.number }} |
| 67 | + PROJECT_NUMBER: "6" |
| 68 | +``` |
| 69 | +
|
| 70 | +{{< screenshot src="github-actions-error.png" alt="GitHub Actions error message" >}} |
| 71 | +
|
| 72 | +The error message wasn't immediately helpful regarding the runner environment: unknown owner type. Why would it suddenly not know the owner type for "socrabytes"? This didn't feel like a gh version compatibility issue on the surface. |
| 73 | +
|
| 74 | +## Isolating the Variable: Local 🆚 Remote Testing |
| 75 | +
|
| 76 | +If it wasn't the runner OS or (maybe) the `gh` version difference, I needed to confirm the command itself was still valid. |
| 77 | + |
| 78 | +1. **Test Locally (Current Version):** I ran the equivalent `gh project item-list` command on my local machine, which had `gh version 2.68.1` installed via Homebrew. **Result: It worked perfectly.** |
| 79 | +2. **Test Locally (Upgraded Version):** To further rule out a breaking change in newer `gh` versions, I upgraded my local CLI (`brew upgrade gh`) to `gh version 2.71.1`. I ran the command again locally. **Result: It *still* worked perfectly.** |
| 80 | + |
| 81 | +This was a critical finding. If the command worked locally with both the older version *and* a version newer than the one on the runner, the `gh` version number itself was highly unlikely to be the direct cause. The problem had to be specific to the GitHub Actions execution **context**. |
| 82 | + |
| 83 | +## Digging Deeper: Checking Authentication in Actions |
| 84 | + |
| 85 | +My workflow uses a Personal Access Token (PAT) stored as a secret (`secrets.PROJECT_TOKEN`) to authenticate `gh` commands, allowing it to modify my project board. Although I knew the PAT *should* be valid (it hadn't been changed recently), the next logical step was to explicitly verify authentication *within the runner environment*. |
| 86 | + |
| 87 | +I added a simple debug command to the failing step: `gh auth status`. |
| 88 | + |
| 89 | +```YAML |
| 90 | +- name: Retrieve Project Item |
| 91 | + id: get-item |
| 92 | + run: | |
| 93 | + echo "gh cli version: $(gh --version)" # Added for good measure |
| 94 | + echo "Debugging OWNER: $OWNER" |
| 95 | + echo "Checking auth status:" # <-- Added this line |
| 96 | + gh auth status # <-- Added this line |
| 97 | +
|
| 98 | + # Original command follows... |
| 99 | + ITEM_ID=$( |
| 100 | + gh project item-list "$PROJECT_NUMBER" # ... etc |
| 101 | + ) |
| 102 | + # ... |
| 103 | + env: |
| 104 | + GH_TOKEN: ${{ secrets.PROJECT_TOKEN }} |
| 105 | +``` |
| 106 | +## The "Aha!" Moment: The Real Culprit |
| 107 | + |
| 108 | +The output from this debug step in the Actions log was crystal clear: |
| 109 | +```CLI |
| 110 | +gh cli version: gh version 2.70.0 (2025-04-15) |
| 111 | +https://github.com/cli/cli/releases/tag/v2.70.0 |
| 112 | +Debugging OWNER: socrabytes |
| 113 | +Checking auth status: |
| 114 | +github.com |
| 115 | + X Failed to log in to github.com using token (GH_TOKEN) |
| 116 | + - Active account: true |
| 117 | + - The token in GH_TOKEN is invalid. |
| 118 | +Error: Process completed with exit code 1. |
| 119 | +``` |
| 120 | + |
| 121 | +There it was: **"The token in GH\_TOKEN is invalid."** The `unknown owner type` error was simply a downstream effect of `gh` failing to authenticate properly *before* it could even process the project and owner details. |
| 122 | + |
| 123 | +**The Resolution: A Simple Token Refresh** |
| 124 | + |
| 125 | +Why was the token invalid? I checked my repository secrets – the `PROJECT_TOKEN` secret itself showed "Last updated 4 months ago". |
| 126 | + |
| 127 | +**(Optional: Insert Image `image_597009.png` here, showing the secrets list)** |
| 128 | + |
| 129 | +However, the "last updated" time for the *secret storage* doesn't reflect the *PAT's expiration date*. PATs are generated with specific lifetimes (e.g., 30, 60, 90 days, or custom). It was almost certain my PAT, likely created with a 90-day expiry, had simply expired. |
| 130 | + |
| 131 | +The fix was straightforward: |
| 132 | + |
| 133 | +1. Go to GitHub Developer Settings -> Personal access tokens. |
| 134 | +2. Find the relevant (likely expired) token. |
| 135 | +3. Regenerate the token, ensuring it had the necessary `project` scopes. I chose a new 90-day expiration. |
| 136 | +4. Copy the new token value. |
| 137 | +5. Go back to the `youtube-digest` repository Settings -> Secrets and variables -> Actions. |
| 138 | +6. Update the `PROJECT_TOKEN` secret with the new token value. |
| 139 | + |
| 140 | +After updating the secret, I re-ran the workflow, and it executed perfectly. |
| 141 | + |
| 142 | +**Lessons Learned & Takeaways** |
| 143 | + |
| 144 | +This half-day troubleshooting journey reinforced several key points: |
| 145 | + |
| 146 | +- **Debug Systematically:** Don't get locked onto the first hypothesis, even if initial evidence seems strong (like runner update warnings). Methodically eliminate variables. |
| 147 | +- **Leverage Local Testing:** Comparing behavior locally versus in CI/CD is crucial for pinpointing environment-specific issues. |
| 148 | +- **Verify Authentication Early:** When CI/CD tools interact with APIs, especially if encountering strange errors, explicitly check the authentication status (`gh auth status` in this case) early in the debugging process. |
| 149 | +- **Error Messages Can Mislead:** The initial `unknown owner type` error sent me down the wrong path initially. The real error was hidden until authentication was explicitly checked. |
| 150 | +- **Manage Credential Lifecycles:** PATs expire! This incident highlighted the need for proactive management. Setting calendar reminders or documenting expiration dates is crucial, even for solo projects. |
| 151 | + |
| 152 | +**Conclusion** |
| 153 | + |
| 154 | +While the root cause – an expired PAT – was operationally simple, the path to diagnosing it involved navigating misleading clues and systematically ruling out other potential causes. It was a valuable reminder that sometimes the most obvious environmental changes aren't the culprit, and checking foundational aspects like authentication is key. Hopefully, sharing this journey helps someone else who encounters a similarly confusing workflow failure! |
