Zoom API - You need to set the "Customer Managed Key" firstly - Code: 1253

Hi all,

   I'm trying to update user setting using PATCH to user setting with Zoom API. I'm receiving this Message with status code 400:

b'{"code":1253,"message":"You need to set the \\"Customer Managed Key\\" firstly."}')

  I'm not using Managed Key in my account. 

The flow is:

- Add user via API. Result: OK

- Read user settings by user id. Result: OK

- Modify license json and PATCH user setting: Result: 400

  What can i do? 

Thanks,
