Hello,

Thank you so much for creating this action! I tried it using the sample code provided in the README and unfortunately got the following error:

Am I doing something wrong?

[pete911]

Hi @maximemoreillon, default charts dir flag is set to "charts", but your charts are located in "food-manager". I have added check if the the directory exists, so it should be much clearer what the error message is (just update to v0.0.7). You can either set charts-dir flag, or rename the directory where you keep charts.

Thanks for raising the issue (I have improved the checks), feel free to close this issue if it fixed your problem.

[maximemoreillon]

Hello @pete911, thanks so much for your quick answer and for the update! The new error message is now much easier to understand.

I reorganized my repo so that my chart is in the charts folder and this step is now working as expected so I will mark this issue as closed.

However, I am now getting a new error during the release step (still using the action from the readme):

Am I missing something else? Should I open a new issue about it?

[pete911]

Hi @maximemoreillon, this is coming from github client, did you create and set github token - -token "${{ secrets.GITHUB_TOKEN }}"

[maximemoreillon]

@pete911 thanks so much for your reply!

I am using the .yml configuration from the readme so the token (if it exists) should be set.

- name: Package and release chart
  run: |
    git config user.email "gh-action@users.noreply.github.com"
    git config user.name "gh-action"
    ./hcr -token "${{ secrets.GITHUB_TOKEN }}"

I might have omitted to create it though. If so, I apologize.

However, I am puzzled as to why the original helm-releaser-action works without me having to do anything particular about it:

- name: Run chart-releaser
  uses: helm/chart-releaser-action@v1.5.0
  env:
    CR_TOKEN: "${{ secrets.GITHUB_TOKEN }}"

[pete911]

Hi @maximemoreillon, not sure why it is failing tbh, because the token is set (log returns ****, if it wasn't set it would log for the token). Plus the error is coming from github itself. Are you still facing the problem, or was it just one off error?

[maximemoreillon]

Hello @pete911 thanks a lot for your reply and sorry for getting back to you late.

The error was recurring so I switched to original helm-releaser-action for my workflows, sorry.
