"Validation failed" creating prettier checks about lint-action

[tractorcow]

Another check in the same repo (eslint: true) passes successfully, so it's not a permission issue. It's only an issue for prettier: true check

How can I get the payload for the HTTP post to debug?

[tractorcow]

I managed to extract the payload that was causing the 422 error. The issue is "path" is a required field, but not included.

{
   "name":"Prettier",
   "head_sha":"8926cd754ef3fc50cf4f605b55fa686f4da2630c",
   "conclusion":"failure",
   "output":{
      "title":"1 error",
      "summary":"Prettier found 1 error",
      "annotations":[
         {
            "path":"",
            "start_line":1,
            "end_line":1,
            "annotation_level":"failure",
            "message":"There are issues with this file's formatting, please run Prettier to fix the errors"
         }
      ]
   }
}

I've tracked the issue to prettier itself; prettier/prettier#13516

I think this module could respond a bit better to prettier erroring. In linters/prettier.js we have this code.

		const paths = output.stdout.split(/\r?\n/);
		lintResult.error = paths.map((path) => ({
			path,
			firstLine: 1,
			lastLine: 1,
			message:
				"There are issues with this file's formatting, please run Prettier to fix the errors",
		}));

However in this case, output.stdout is blank (hence path being an empty string), with the error being in output.stderr.

Updating prettier in my project seemed to solve the issue. I'll close this, sorry for the noise!

I've suggested a minor improvement at #722 to prevent invalid checks being pushed.

Checking output.stderror this is that value. Should I bother to parse this?

[error] src/components/Icon/Icon.stories.tsx: SyntaxError: ',' expected. (32:3)
[error]   30 |     },
[error]   31 |   },
[error] > 32 | } satisfies Meta<typeof Icon>
[error]      |   ^
[error]   33 |
[error]   34 | export default meta
[error]   35 | type Story = StoryObj<typeof Icon>

I could regexp the first line and extract path, error, line, character?
