UPDB OIDC login returns wrong content type

[andrewpmartinez]

Experienced

Using the incorrect credentials for UPDB logins on edge-oidc API returns a 401 correctly, but returns a content type of text/html instead of application/json when the Accept header only specifies application/json.

Expected

Correct content type negotiation to application/json

Reproduction

1. Deploy a controller w/ edge-oidc enabled as an API
2. Attempt to use UPDB over OIDC authentication with bad credentials
3. see a 401 w/ text/html response
