Magic's sdk uses a package called webcrypto, which will occasionally throw an error like this:
webcrypto TypeError: Failed to execute 'sign' on 'SubtleCrypto':This shouldn't affect your app's performance or the login flow at all and can be ignored. If you're experiencing any blockers in addition to the webcrypto error, please let us know and we're happy to help out.
parameter 2 is not of type 'CryptoKey'.
