OAuth app fails to redirect to sign in page

Greetings,

I currently have an Intercom app that seamlessly integrates with our system and our customers' accounts. However, I've observed an unusual behavior during the OAuth process when a user attempts to navigate without being logged in. Intercom redirects the user to the sign-in page but returns an "unexpected error" message due to the inclusion of OAuth query parameters.

Has anyone encountered a similar issue and found a viable solution? I have attached a screenshot illustrating the error for reference.

Thank you in advance for any insights or assistance provided.
