rmapy error when reading the .rmapi directory

[adaptiman]

When executing the program with both Docker and Python methods, I get the following stack-trace and error. It appears that rmapy is trying to read '/home/appuser/.rmapi as a file rather than the directory that it is. Here's the stack trace:
