Hello guys, for months now I have been using the auth0-spa-js SDK with my dev tenant and my dev application for login. await createAuth0Client({ domain: 'my-domain', client_id: 'xyz012', audience: undefined, // remember this, it says it is optional redirect_uri…

If you decode a JWT from your first tenant, does it have an aud claim set to anything? Also, under your tenant settings > General > API Authorization Settings, there is a “Default Audience” setting. You may want to check if you have something there for your first tenant and not for your second.

Audience yes, no, why?

Hi @sebastian.richter,

It is optional, but you shouldn’t return a JWT if there isn’t a registered audience as the param.

In the application that is returning a JWT, what is the aud claim? Undefined?
