Thanks for fixing this, @seve ! Not sure why it suddenly started failing the lint GHA 🤔

[tihuan]

@seve can you give the team a headsup that you're fixing the lint GHA error, so people know it's being taken care of? Thank you!

[tihuan]

so this will be node-version-file: "frontend/.nvmrc" too?

[seve]

with an update to v4 as well, I'll do other edits in a separate PR to quickly unblock merges to main

[tihuan]

That sounds good thank you!

[tihuan]

and do we need to bump this version to 4 or is it not blocking?

[seve]

non-blocking

[tihuan]

Awesome thanks!
