I'm having the exact same issue. The actual creation of the analysis data works nicely. However, when the cron based schedule is started as an action I get the same error as described above:

Thanks for the report. We believe we've fixed it at head -- see #73

I'll cut a release tomorrow and this should fix it. Sorry for the inconvenience. cc @azeemshaikh38

I've updated the workflow to v1.0.4 which I assume is the version you have released the fix with. I'll report back in terms it does not work for me. Thank you

[laurentsimon]

please report even if it works, so that we can confidently say this is fixed

hi @laurentsimon,

Its not working for me! I am on 1.0.4

here is the build -> https://github.com/SchwarzIT/node-red-chart/runs/5304079801?check_suite_focus=true

[laurentsimon]

Thanks for the report. I tried just now on a test repo and it worked https://github.com/laurentsimon/scorecard-action-test-2/runs/5310937149?check_suite_focus=true

I ran the command we use in the action that retrieves the values that are null in your run (https://github.com/ossf/scorecard-action/blob/main/entrypoint.sh#L50-L54):

export REPO=SchwarzIT/node-red-chart
curl -s https://api.github.com/repos/$REPO | jq -r '.default_branch'

and it works.

Could you run the command above with your PAT token, as in these lines https://github.com/ossf/scorecard-action/blob/main/entrypoint.sh#L50-L54? Either there's something special about your PAT, or something special about your repo when it runs on push (?)

If that does not help us figure the problem, I'll create a branch that prints the results of API calls and we can see what's happening.

Thanks!

hi @laurentsimon,

it works now, I recreated the PAT token. I don't know what could be the reason? Maybe PAT not valid anymore (dont know if I set the date no never experire or standard 30d).

Nevertheless, thanks for the help and your work!

[laurentsimon]

Nice!

It would be useful to use your old PAT and see the results of the curl command above, if you still have the PAT saved and available :-)

[schaefi]

please report even if it works, so that we can confidently say this is fixed

I can confirm it works again in my workflow. uploading failed but that could be an issue on my side. Thanks

[laurentsimon]

Thanks, closing this issue then.
