Run faild:io.grpc.StatusRuntimeException: UNKNOWN about milvus-sdk-java

[yhmo]

Which version of your java sdk and milvus?
I just use Java SDK 2.3.3 and Milvus 2.3.3 to run the SimpleExample.java, it works well.

[alexanderankin]

i had to set grpc version to io.grpc:grpc-netty:1.60.1

here is a reproducible test case alexanderankin/how-to-itest@32ddec4 - remove the line and it fails

if its the same issue I'm facing, here is the relevant part of the stack trace:

the same method is implemented in 1.60.1

i had to set grpc version to io.grpc:grpc-netty:1.60.1

here is a reproducible test case alexanderankin/how-to-itest@32ddec4 - remove the line and it fails

The java.lang.UnsupportedOperationException caused by io.grpc.netty.AbstractHttp2Headers.isEmpty has been fixed in the v2.3.4 by upgrading the grpc version to 1.59.1.

But this error I think is different, the root cause is unknown:

io.grpc.StatusRuntimeException: UNKNOWN
at io.grpc.stub.ClientCalls.toStatusRuntimeException(ClientCalls.java:271)
at io.grpc.stub.ClientCalls.getUnchecked(ClientCalls.java:252)
at io.grpc.stub.ClientCalls.blockingUnaryCall(ClientCalls.java:165)

I was seeing those same stack trace lines in the top half of my exception stack trace, but I omitted them, because I didn't think it was relevant. The two parts of the overall stack trace happen on different threads, in my understanding

[alexanderankin]

thank you for fixing this in latest release! verified and upgraded my repo of examples in alexanderankin/how-to-itest@e6be074

hope we hear back from the original poster to find if that is the same issue or not.
