Hello! My company uses a self-hosted GrowthBook, currently version 2023-11-27. I am trying to automate the process of launching A/B tests. I successfully managed to create a feature with API request, but I’m unable to create an experiment and link it to the feature—it returns a 400 error (example of error: b’{“message”:“Invalid data source: “}’;). I don’t have datasources and can run experiments without it using admin panel. The documentation seems to be written for the latest version. Is there any way to access documentation specifically for version 2023-11-27 to see all possible parameters? Here’s the python code I have right now. I would greatly appreciate your help and thank you in advance!
