An update of a schema index can result in a 500 Internal Server error when there are no changes to be made, this means that the field values are identical to the current ones. Performing a GET request on the API to check the indices reveals that no update is required, as the index is identical to the body provided in the PUT request.

Simulation

1. Send a PUT request to update a schema index through the API, providing the necessary payload in the request body.
2. Verify the response from the API and observe if it returns a 500 Internal Server Error.
3. Perform a subsequent GET request on the API to retrieve the schema indices and compare them to the body provided in the PUT request.
