Webapp Server not starting.

[Gilbert2015]

During the deployment of the webapp server using the webapp docker image, I faced an error stating that the application could not write to the log file. Here is the log output from the deployment:

"The connection to the database was successful, but the application failed to open the log file."

Please check the permissions for /usr/local/homer directory or start the homer-app under root

@adubovikov Thank you so much for your response. After setting the permission for /usr/local/homer, the application was able to write log file. I am now getting the error message "level":"FATAL","prefix:"echo":"file":"main.go","line":"882","message":"Couldnt start server"
