GitHub Actions / Best practices for writing actions

Stringify objects when using core.* utilities to output logs

Objects are expected to be supported sooner or later.

GOOD

try {
  await run();
} catch (err) {
  core.setFailed(err.toString());
}

// => ::error::HttpError: Not Found

BAD

try {
  await run();
} catch (err) {
  core.setFailed(err);
}

// => UnhandledPromiseRejectionWarning: TypeError: (s || "").replace is not a function
