"Internal Server Error" when login to Fief in browser after HTTP/PATCH via REST API

[Kh-Oleg]

Describe the bug

When I try to login to Fief in browser after modifying the Fief's client via Admin REST API, I see "Internal Server Error" in the browser.

To Reproduce

Steps to reproduce the behavior:

1. Start Fief with the initial Admin Key
2. Go to /admin/api/docs
3. Authorize with the Admin Key
4. Execute GET /clients/ to see the parameters of the existing client, it's "Fief's client"
5. Go to PATCH /clients/{id}
6. Enter id from the step 4 to the id's field
7. Enter redirect URIs from the step 4 to the PATCH payload
8. Enter client name from the step 4
9. Execute the request, you should get 200 OK and a valid response body
10. Now open browser and open Fief's admin page, /admin
11. Fief will ask to login
12. After entering the admin's credentials, browser shows "Internal Server Error"

Expected behavior

A Fief dashboard shall be shown after a successful login.

Configuration

• If self-hosted, Fief version: 0.24.3 - 0.25.1

Additional context

Fief doesn't print any call stack to console in this case.
