Query to api/targets raises server error 500

Describe the bug I have a data pipeline with a function designed to upload target lightcurves (in CSV format) to my TOM, using the TOM's APIs. Specifically, it uses this module for the upload, which calls the TOM functions in the pipeline's tom.py module.

The issue is raised in tom.get_target_id when the server returns a 500 status code.

To Reproduce

Nothing was logged in stern when I tested this with MOP in operation, so investigating this on my test server, I re-created the query:

targetid_url = BASE_URL/api/targets/ params = {'name': 'OGLE-2024-GD-0006'} (as an example)

response = requests.get(targetid_url, auth=login, params=ur)

The trackback from my test server is as follows:

Expected behavior This module of the pipeline has been uploading lightcurve data for some time, and hasn't changed recently, so it seems likely this is related to implementing the custom target model.
