Describe the bug

When trying to obtain a token using the device code authorization flow I cannot enter the user code manually in the form given by verification_uri. After entering the correct code and pressing submit, an error is displayed.

If I go directly to the verification_uri_complete URL (i.e. with ?code=) then it does work.

To Reproduce
Steps to reproduce the behavior:

1. Create a new stage configuration flow. Set require authentication (I have also tried with no authentication)
2. Change the brand's device code flow to this flow (I have also tried default-source-pre-authentication)
3. Create an application with the OAuth provider. Set credentials type to public.
4. Initiate a device code authorization flow through /application/o/device
5. Navigate to the verification_uri given in the response and enter the user code
6. Press Continue
7. An error is displayed

Expected behavior

Entering the code in the form should work the same way going directly to verification_uri_complete does

Version and Deployment (please complete the following information):

Additional context

If there is specific configuration I need for the device code flow then it isn't documented anywhere.

I have tried the above steps in a private browsing session to no effect.

I have not been able to find any logs anywhere to indicate the underlying trace for the error displayed.
