Describe issue

YAML linting of workflow files is too aggressive and doesn't respect valid input

According to GHA docs, an expression is valid for timeout-minutes.

Additional information

Is there a work-around to disable linting? It's putting me in a position where I need to do testing on github itself.

It's not linting, it's parsing the yaml

well either way it's incorrect, because it throws an error for valid github workflow syntax.

Why was this closed? I'm experiencing the same due to the following, which is valid and used in production workflows.

Error: yaml: unmarshal errors:

You need write valid yaml syntax. Use a yaml linter.
