[fhir-client] Calling $validate from the fhir-client fails in the main branch

[vikforfda]

We are using the FHIRClient validate method to validate Bundle resource by passing the Bundle object.

client.validate(finalBundle)

It fails to perform validation. The FHIR server log displays following message

Following is a sample Bundl resource that has validation error but the validation operation does npt detect it

Thanks Vikas. It looks like the client was dependent on $validate being served at [base]/Resource/$validate.
We used to support that but I removed that support in #3265.
I think we'll need to update the client to infer the resource type from the resource that was passed.

@vikforfda what kind of object is your finalBundle?

our FHIRClientImpl validate implementation is already invoking validate on a type-specific basis, and so I now suspect this is an issue with your code and not ours.

closing as unable to reproduce

The issue was on our side. We were using an older version of fhir client to invoke the validation operation API. After we updated it to use versions 4.11.1 (most recent IBM-FHIR release) or 5.0.0-SNAPSHOT (corresponds to the WIP IBM-FHIR R4b release) then the validation correctly identified the error
