[oliveregger]

GET https://test.ahdis.ch/mag-pmp/fhir/Patient/$ihe-pix?sourceIdentifier=urn%3Aoid%3A2.16.756.5.30.1.196.3.2.1%7CBADPATIENT001&targetSystem=urn%3Aoid%3A2.16.756.5.30.1.127.3.10.3 HTTP/1.1

return HTTP error 400

For this specific request, the 404 is correct, the detailed message is sourceIdentifier Assigning Authority not found
and according to https://profiles.ihe.net/ITI/PIXm/ITI-83.html#23834223-source-domain-not-recognized this should
be returned with an OperationOutcome and 404 (there are others with 400 and 403).

Please recheck the spec (at the above provided link). For the Assigning Authority domain not found case error 400 is correct. For patient identifier not found it is 404.
