error running the app: Not Found

[gelo22]

Command:
docker run slok/alertgram:latest --telegram.api-token=bot000000000:AAAAAAAAAAAAAAAAAAAAAAAAAAA-aaa --telegram.chat-id=-00000000
Result:
error running the app: Not Found

Same with --debug, non default ports and so on
Only running with: --notify.dry-run

docker run -p18080:18080 -p18081:18081 slok/alertgram:latest --telegram.api-token=bot000000000:AAAAAAAAAAAAAAAAAAAAAAAAAAA-aaa --telegram.chat-id=-00000000 --metrics.listen-address=":18081" --alertmanager.listen-address=":18080" --debug --notify.dry-run

Unfortunately in my case - this code is waste of time.
Just wandering why with --debug options the code returns same short message for mind-readers
