FIX: JODConverter container fails to start due to "Config data location '/etc/app/' does not exist" error.

In the past week, I've created several Docker-based BBB 2.3 installations using the process I detail here. The problem I've suddenly encountered (implementations more than about a week old) do not exhibit this issue) is that the JODConverter container consistently fails on start with the following error:

22:14:17.856 [main] DEBUG org.springframework.boot.diagnostics.LoggingFailureAnalysisReporter - Application failed to start due to an exception

Description:

Config data location '/etc/app/' does not exist

Action:

Check that the value '/etc/app/' is correct, or prefix it with 'optional:'

I have managed to fix it by altering the following file mod/jodconverter/Dockerfile adding the following line at the end:

CMD ["--spring.config.additional-location=optional:/etc/app/"]

to add the "optional:" prefix to the additional-location directory. After an ./scripts/upgrade, the jodconverter container is rebuilt and runs fine.

It appears that the upstream jodconverter developer (or even his upstream) has upgraded versions in the past 8 days or so, which has led to the problem.

Hope this helps someone.
