Cannot sign up.

[MTtheman]

I cannot sign up on my first startup of the application. Server OS: Alpine Linux Host OS: Arch Linux Host Browser: Firefox. I get these two errors as highlighted in the attached image. Thanks

Check the logs from browser console & server side.

[MTtheman]

Where would I find the logs?

[CodeWithCJ]

Based on what browser you use, google it to find how to get browser console log. IN chrome, its under three dot-->More Tools-->Developer Tools-->Console.

run below command to get the container id and then run second command.
docker ps

docker logs <container_name_or_id>
