Hello @denniscalazans ,

I am not seeing the error you mentioned when I use auth0-spa-js@2.1.3 along with angular@17.3.0. Can you share your package.json here ?

Additionally, could you provide a code snippet demonstrating how you are using auth0-spa-js@2.1.3 ?. This would be helpful.

I'm having the same problem. We've implemented our own ICache, and configured that in Auth0.config.cache. That seems to cause it, reverting back and using the default 'memory' or 'localstorage' option does not cause this error to occur.

I've set "noImplicitReturns": false in our own tsconfig.json to fix this but that is less than ideal
