rasa: Unable to update config.yml in Rasa X

Rasa version: 2.2.7-full

Rasa SDK version (if used & relevant): 2.2.0

Rasa X version (if used & relevant): 0.35.0

Python version: 3.8

Operating system (windows, osx, …): Amazon Linux

Issue: I am not able to update the configuration file. Each time I attempt to do so, I receive a 422 error. In addition, syncing with Github also does not appear to modify the config file. This error still occurs after disconnecting from Github. It is present on this version and also the 0.33.0 version used before.

Error (including full traceback):

Command or request that led to error: Manually updating the configuration file by adding the following line:

Also occurs by just removing anything or any other changes.
