I'm trying to integrate safe-global/auth-kit and upon initialization of SafeAuthPack I'm getting CORS issues on localhost. Is there any workaround for this?

It seems that the txServiceUrl: "https://safe-transaction-polygon.safe.global" is incorrect, URL should be https://safe-transaction-polygon.safe.global/api.

Since the SDK will automatically map the correct URL to the chain you are using, you can actually remove this parameter entirely and simply do new SafeAuthPack().

Hope it helps! Best, Louis
