Coverage report fails after 65536 characters

The GitHub comment maximum length is, apparently, 65536 characters (though I suspect they might mean bytes):

RequestError [HttpError]: Validation Failed: {"resource":"IssueComment","code":"unprocessable","field":"data","message":"Body is too long (maximum is 65536 characters)"}

Having encountered a coverage report that surpasses this limit, and knowing the repo in question will only continue to have lengthier reports in the future, I’d like to find ways to shorten the report, or possibly split it across multiple comments.

I realize I could resort to an external coverage reporting tool, but I’d prefer to keep everything in one place. (Plus, with private repos, the cost of external tools gets really high really fast.)

Had same problem, and because it looks like this bug is open for long already I forked and modified it to not send link to every line that was not covered. Feel free to use it:

    - name: Report coverage
      uses:  mszlgr/lcov-reporter-action@v0.2.23

Also this action failed for me when run on below trigger (it assumes that it is pull request), that was also fixed in my fork.

on:
  push:
    branches: [ master ]
