Steps to Reproduce

• Issue is reproducible when the U2 level is less than 77 by following the steps outlined below. Please note that the issue is also reproducible for U2 levels higher than 77 if a subdirectory is created under the /documentation registry path with an Unknown Media Type.

1.Add an API Document under subdirectory using the below Publisher REST API [1].
Sample CURL

curl --location 'https://127.0.0.1:9443/api/am/publisher/v4/apis/2b56e273-2e0f-46e3-aee7-4115258a62db/documents' \
--header 'Authorization: Bearer 80d7d972-c55b-34bb-a606-aea385945a66' \
--header 'Content-Type: application/json' \
--data '{
  "name": "ttttt/PizzaShackDoc",
  "type": "HOWTO",
  "summary": "Summary of PizzaShackAPI Documentation",
  "sourceType": "INLINE",
  "inlineContent": "This is doc content. This can have many lines.",
  "visibility": "API_LEVEL",
  "createdBy": "admin"
}'

2 - Try to save the API via the Publisher portal.
