What version of iOS SDK are you using?
and do you have a sample of your JWT token as well?

Zoom SDK version: v5.15.7.9685

Here is sample token CnsKCiJhbGciOiAiSFMyNTYiLAoKInR5cCI6ICJKV1QiCgp9Cg.CnsKCiJhcHBLZXkiOiAicnBhRjRYWlpUUlNXYjJyM0d1Vm53IiwKInNka0tleSI6ICJycGFGNFhaWlRSU1diMnIzR3VWbnciLAogInJvbGUiOiAiMCIsCgoibW4iOiAiODkyMTE3Mzc1MTUiLAoKImlhdCI6ICIxNjkyMjY5MDg3OTcxIiwKCiJleHAiOiAiMTY5MjM1NTQ4Nzk3MSIsCgoidG9rZW5FeHAiOiAiMTY5MjM1NTQ4Nzk3MSIsCgoidXNlcklEIjogIjEyMzQ1Njc4OTAiLAoKInVzZXJOYW1lIjogIkpvaG4gRG9lIgoKfQo.lJI10tK-nkBoXVsvOV_c4NbjXKoJVtRJ8dA0ZfyMmHk

@streamerz.ltd ,

Your iat, exp and tokenExp are invalid integer values
