**Description**

Following the recommendation of the documentation for initializing the sdk using jwtToken, no matter how I generate the token, it always returns error code 1, if using appSecret and appKey, everything works normally.

Hi @elias.ferreira,

Thanks for the post. The `tokenExp` should be a timestamp that is at least 30 mins later than the `iat`, so it would be `tokenExp` = `iat` + 3600

Please have a try.

Thanks!
