I'm trying to use the IBM Cloud Db2 API to list all my schemas (a simple use of the API), but I'm getting an unexpected internal error, and I can't find a way to figure it out.

The documentation link: https://cloud.ibm.com/apidocs/db2-warehouse-on-cloud/db2-warehouse-on-cloud-v4#listdatabaseschemas

Command:

curl -X GET \
   https://{HOSTNAME}/dbapi/v4/schemas \
   -H 'authorization: Bearer {AUTH_TOKEN}'\
   -H 'content-type: application/json'

Error:
