Thanks for the testing this Kevin I really appreciate it.
I went back and took another look and I've figured out my mistake. I was following the instructions to enable tenancy from HAPI FHIR, but the project I'm using hapi-fhir-jpaserver-starter has a configuration in application.yaml to enable tenancy.
I had added these lines to JpaRestfulServer.java:
```
myPartitionSettings.setPartitioningEnabled(true);
setTenantIdentificationStrategy(new UrlBaseTenantIdentificationStrategy());
registerInterceptor(new RequestTenantPartitionInterceptor());
```
That sort of enabled tenancy. But something about that must conflict with hapi-fhir-jpaserver-starter.
I don't need those at all, I just needed to uncomment these lines in application.yaml:
```
partitioning:
allow_references_across_partitions: false
partitioning_include_in_search_hashes: false
```
Now I can create partitions as shown in the docs.
thanks,
Andrew
