[BUG] Could not pull latest version information: SyntaxError: Unexpected token '<', "<!DOCTYPE "... is not valid JSON

[nitram509]

Describe the bug

I'm using codecov@v4 action in my Open Source project since a while,
but today I got this error message and my GH actions 'on merge PR' did fail with error:

(snipped from GH action log

To Reproduce
Steps to reproduce the behavior:

1. Using dependabot, which proposed an upgrade of a lib
2. On PR, GH Action was triggered
   • here the codecov uploader did fail, unexpected
   • see https://github.com/nitram509/ntgrrc/pull/89/checks

See CI link below for full log.

Expected behavior
Guessing there was an issue with rate limiting or other reasons why the access to the codecov server did fail,
but I expect better error handling and seeing reasonable error messages, so I understand what to do.

Versions

• OS: ubuntu-24.04-arm
• Git Host: Github
• Uploader 'codecov/codecov-action@v4' (SHA:b9fd7d16f6d7d1b5d2bec1a2887e65ceed900238)

Commit and CI link

@nitram509 this looks like a one-off, you shouldn't receive that error on retry. Please upgrade to v5 if you are still experiencing the issue.

It seems to actually happen persistently on ARM machines (Sadly it's a private project and private github hosted runner so I can't share logs/links)

[thomasrockhu-codecov]

@elichai have you tried setting the os: arg to the proper ARM version? You can see values here: cli.codecov.io
