Errors while creating an application through okta api

@bdemers Can you please check this error and help if there is any issue in the payload or anything else in the calling python code?
After fixing the the name field, I get this error:

{ [{‘errorSummary’: ‘Cannot create application instance. Maximum number of instances has been reached.’}]}.

However I am able to create an app from the GUI, any restrictions on API side? What is the reason for this error?

Can you please confirm asap if there are issues calling the APIs from python code as per this thread?

Or else I need to switch to Java or any other language?
