Helped me through, despite not being the same problem the use the URL quote helped me solve this by changing a bit how I thought about it!

The final result became a little too big to paste here, but the handling ended up being relatively straightforward:

  useEffect(() => {
    if (result?.type === "success") {
      const { token, iv } = getParamsFromUrl(result.url)

      const session = decrypt(token, key, iv)
      console.log({ session })
    }
  }, [result])

Update: found the issue. It was caused by the discovery failing silently. The example code is not well engineered here. There should be a check (even in the example) that detects errors when doing the discovery part.

If you are encountering this, make sure the actual endpoint URL delivered to the auth mechanism is actually set from the discovery.

Try this:

-Login to your expo account: on command line type:

expo login
##then your account credencials##

then restart your expo instance:

expo start

And everything should work fine
