run reviewdog in github actions: scheduled run fails

[kkania-splunk]

Hi,
We're using reviewdog in our CI in 1 of our actions
https://github.com/splunk/addonfactory-sample-scanner/blob/ec63afb345140ee3e3aeae8ee681bc5220d9ae73/entrypoint.sh#L58
it works very well for PR and push events but it fails for scheduled runs with an error
reviewdog: post failed for addonfactory-sample-scanner: failed to create check: POST https://api.github.com/repos///check-runs: 404 Not Found []
do you think it is possible to have the same CI steps including review dog for all events (PR, push, schedule)?
