GeneratedMessageV3.isStringEmpty NoSuchMethodError issue

[armmarov]

Hi,

I am using the fabric-gateway-java sdk for my api server connected to hyperledger. When it tries to call below function, seems like some error appear from fabric-sdk-java-2.2.11. Not sure if having compatibility issue with protobuf GeneratedMessageV3. Could you please help me on this ? Should I reduce the version to 2.2.10 ?

Update

When i override the dependency to 2.2.10, it seems working fine. Maybe have some compatibility issue that you want to check ? Thank you.

<dependency>
    <groupId>org.hyperledger.fabric-sdk-java</groupId>
    <artifactId>fabric-sdk-java</artifactId>
    <version>2.2.10</version>
</dependency>

The v2.2.11 release did update the versions of gRPC and protobuf packages in its dependencies. They are very sensitive to version changes so fabric-sdk-java uses the same protobuf package version as the grpc-protobuf package it uses. If you have any explicit protobuf (or gRPC) dependencies in your application, that might override the versions in the fabric-sdk-java dependencies and cause a conflict.

Right now the fabric-sdk-java and fabric-gateway-java nightly builds are continuing to run successfully so this doesn't appear to be a general problem with those packages.

I can't reproduce this issue locally. Were you able to get things working OK? If so, it would be useful to know the cause and solution.
