Package inconsistency between versions. Error: 'str' object has no attribute 'get' in yatter 1.1.4

[TheRazorace]

The following YARRRML excerpt does work with Yatter v1.1.0 (Python 3.9), but does not work with Yatter v1.1.4 (tested with Python 3.9 and Python 3.12), even though the syntax is the same and seems correct, according to documentation.

Error: The YARRRML mapping has not been translated. 'str' object has no attribute 'get'

Hi @TheRazorace, I think I found the problem and fixed it in dev branch, could you test it?

Thanks for the reply @dachafra! I can confirm that the problem is solved using the fix in the dev branch :)
