ServiceX fails to report science image missing under certain circumstances #540
Description
Describe the bug
This crash when running:
servicex.utils.ServiceXException: (ServiceXException(...), 'ServiceX rejected the transformation request: (400){"message": "Failed to submit transform request: Expecting value: line 1 column 1 (char 0)"}\n')Can with some deeper debugging be tracked to:

To Reproduce
Steps to reproduce the behavior:
- Specify a docker science image with two namespaces:
sslhep/sslhep/servicex_func_adl_xaod_transformer:v1.1.4 - Run the transform.
Expected behavior
A clear message declaring the image could not be found. The error should include the image that it was trying to look up so the user can try to track this back to something they did (or how SX was misconfigured).
