Hi! I'm trying to use the migration tools from https://github.com/awslabs/ros2-migration-tools##filling-the-mappings without much success. Surprisingly, my cursor becomes a + and I need to click 6 times!!! Then I get the following erros:

import-im6.q16: attempt to perform an operation not allowed by the security policy `PS' @ error/constitute.c/IsCoderAuthorized/408.

I tried with the Dockerfile added on this fork. Now seems to go further, but I get the error

FileNotFoundError: [Errno 2] No such file or directory: 'mapping/master_mappings.json'

The documentation explains how to create a mapping file, but without any example I'm completely lost about how to do it!

So does anyone succeeded using the tools? Can you provide an example mapping file?

Thanks a lot!
