SDK internal error on auth

I tried to get started with zoom desktop SDK and I got SDKERR_INTELNAL_ERROR response every time when I called m_AuthSDKWorkFlow.Auth(param).
I tried c++ and c# versions - result the same.
What is wrong?


To Reproduce
1 On the first form press button “SetDomain”. “” in the field
2 On the second form enter JWT Token in the field and press “Auth”
I got error “auth sdk failed”. In the debugged I can see it is SDKError::SDKERR_INTELNAL_ERROR(15)
