Hi experts,

Some requests to the Immunization endpoint fail with 504 error. I think they fail if a patient has many immunization records. Is it possible to fix this issue in the sandbox backend?

endpoint: https://fhir-ehr.cerner.com/r4/ec2458f2-1e24-41c8-b71b-0e701af7583d/Immunization?patient=12724066

Hi!

I am seeing the same issue in the sandbox. Trying to test Immunization.search.
