Hi Zoom team,

Thank you for the 6.0.0 release!
I have a question regarding the error codes mentioned in this changelog.

The changelog states:

“Enhanced error code handling for obfToken/recordingToken with error codes 4016, 4017, and 4018”

However, when I checked the official Error Codes documentation below, I couldn’t find any information about these specific codes (4016, 4017, and 4018).

Could you please explain what these new OBF-related error codes mean and in what situations they occur?
Also, it would be greatly appreciated if you could update the documentation to include the details for these codes.

Thank you in advance!
