Unable to create output and permission denied

[SasmonMing]

Hi, I am fairly noob at coding and I encountered this issue, was wondering if anybody could help me out. After I press "q" to record, there are a few lines that's saying:

[] 2024-08-30 22:50:38 - INFO - Output contains undefined placeholder(s). Leaving output unchanged.
[] 2024-08-30 22:50:38 - ERROR - Could not create a directory 'None'
[out#0/mp4 @ 000002757413ef00] Error opening output TK_116tn__2024.08.30_22-50-33.mp4: Permission denied
Error opening output file TK_116tn__2024.08.30_22-50-33.mp4.
Error opening output files: Permission denied

here is the full pic

Hopefully someone can help me out, thanks in advance !

Post your full command and platform. It seems like you might be trying to write to your root folder. Try specifying a different path via "-output" argument. For example, "$EXTERNAL_STORAGE/Movies" on android.
