Outputs

The comment-id, comment-body, comment-author and comment-created-at of the matching comment found will be output for use in later steps. They will be empty strings if no matching comment was found. Note that in order to read the step outputs the action step must have an id.

Tip: Empty strings evaluate to zero in GitHub Actions expressions. e.g. If comment-id is an empty string steps.fc.outputs.comment-id == 0 evaluates to true.
