422 Client Error on FMC 6.2.2

[netman2048]

I'm trying to use this on an older FMC to pull data from to build a new FMC on 6.7 code. When I try to create the FMC object, I get a 422 client error, but I can connect to the new FMC just fine. I'm thinking it is an issue with the older FMC version and the API it presents. I did confirm the REST API is enabled on the old server.

Here is the error I get:

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

The first supported release for FireREST is 6.6.0, theoretically a lot of stuff should work in previous versions but I have no plans to backport fixes to EoL releases. I am open to pull requests if they do not break existing functionality.

OK no problem.... I'll probably just pull what I need with requests myself then use your repo to create stuff in the new. Thanks!
