Image Upload API_ERROR

Hello, I am currently trying to attach images to some catalog items but I am receiving a 500 response along with the following details:

  "errors": [
      "category": "API_ERROR",
      "code": "INTERNAL_SERVER_ERROR",
      "detail": "An internal error has occurred, and the API was unable to service your request."

My sandbox application id is: sq0idp-yuhb9oYugWYOypS0wGS_AA

Usually, I do a batch insert with all the images too, but I am getting that 500 response so I figured I’d give the API Explorer a shot, and the same response is coming back.

Any help to get this resolved would be much appreciated.
