Unknown field found while parsing JSONEachRow

I have setup Senty on-premise with version 10.

Whenever I’m receiving any error I’m getting below error. These are logs from docker-compose.

Can anyone please help me to find the root of this cause?

I really need to fix this. It would be great help if someone can let me know what I’m doing wrong.

If needed I can also provide the sentry_install_log for this installation.

This has been resolved in this git issue.
