diagnostic HAPI-2024 when expanding a valueSet by /$expand?url=

[Rosnyni]

Bug description

Expanding a ValueSet with $expand?url= did not work

Bug reproduction

The bug is rather random, affecting a limited number of ValueSet on my HAPI instance. I can't reproduce it on the http://hapi.fhir.org/baseR4.

however, on the instance installed locally :

Step 1

I have ValueSets (and corresponding CodeSystems), like :

The following GET query is working : https://hapi-fhir-server-qua.exemple.fr/fhir/ValueSet/$expand?url=https://aphp.fr/ig/fhir/eds/ValueSet/aphp-eds-name-space-vs

Step 2

restart the server

Step 3

The above-mentionned query is not working :

while https://hapi-fhir-server-qua.exemple.fr/fhir/ValueSet/aphp-eds-name-space-vs/$expand works.

Expected behavior

I believe this query : https://hapi-fhir-server-qua.exemple.fr/fhir/ValueSet/$expand?url=https://aphp.fr/ig/fhir/eds/ValueSet/aphp-eds-name-space-vs

should have produce a valid expansion of the valueSet

Environment

• HAPI FHIR R4 Server - 7.0.2
• OS: Linux
• edge, firefox, postman

Additional context

Deleting and creating CodeSystems and ValueSet resolve the issue...
