Coverage fails on tagged release "No commit for SHA ..."

[borislemke]

When running coverage report action on a tagged release, we get an error with following details:

RequestError [HttpError]: No commit found for SHA: xxxxxxxx
    at /home/runner/work/_actions/romeovs/lcov-reporter-action/v0.2.19/dist/main.js:6018:23
    at processTicksAndRejections (internal/process/task_queues.js:93:5)
    at async main$1 (/home/runner/work/_actions/romeovs/lcov-reporter-action/v0.2.19/dist/main.js:22998:3) {
  name: 'HttpError',
  status: 422,

This works fine for the main branch though. I reckon this might not be specific to this GitHub Action and something else, but wanted to share this here in case anybody has stumbled upon the same and found a solution.

This horrible thing took a lot of my time.
I've experienced it in a different workflow.
Make sure you checkout to a branch, since tags checkout to a commit, whatever that means.
target_commitish in event context - VERY POORLY documented

- uses: actions/checkout@v3
  with:
     ref: ${{github.event.release.target_commitish}}
