Error parsing the plugin name from processed template

[ahmetb]

I'm getting an error like:

...
time="2022-08-29T21:16:48Z" level=info msg="downloaded file /tmp/768358419/1661807808"
time="2022-08-29T21:16:48Z" level=fatal msg="failed to get plugin name from processed template.
err: error converting YAML to JSON: yaml: line 19: did not find expected '-' indicator"

I'm using rajatjindal/krew-release-bot@v0.0.43 action.

My template looks like the following:

When I run the command locally, it still prints that same error as a fatal error.

But sometimes it prints the error before printing the YAML manifest, and sometimes after the YAML.

Makes me think there's a concurrency issue.

[rajatjindal]

this is due to indentation of yaml lines. i have submitted PR with the fix to kubectl-foreach repo

[ahmetb]

Interesting, because I copied the template as is with the same indentation from kubectl-tree repo. But that uses a much older version of the action.

[rajatjindal]

Hey Ahmet

I just looked into kubectl tree and it seems like it has the right indentation.

Is it possible that maybe the code editor changed it on save?

[ahmetb]

Yeah, it turns out everything got indented, I blame IntelliJ IDEA. Thanks for looking into this.
