Is there a way to disable the tracingEnabled option used in ManagedChannelImplBuilder?

[zerocooldog]

I 'm only using the gRPC client, so I added three basic libraries as dependencies.

After that, I customized the package using shadowJar.

However, after implementing the client and communicating with the server, I encountered the following error. (Even though the error message appears, it seems that communication is working well.)

I found and analyzed the source of ManagedChannelImplBuilder, and I see that the tracingEnabled value is processed when it is set to true.

However, I don't know how to disable this option.

Is there a way to do it?

ps. The same error message is displayed even without using shadowJar.

grpcVersion = "1.68.0" // CURRENT_GRPC_VERSION

    implementation "io.grpc:grpc-stub:${grpcVersion}"

That says "DEBUG." That's not an error. This is regular and expected behavior.

[zerocooldog]

I'm aware that it's related to debugging. I asked because I don't want to see the stack trace. I was wondering if it was possible to disable the output in debug using the tracingEnabled option.

Is there no way to handle this other than changing the log level for that specific package?

Correct. There is a way to configure it and it's to turn off debug logs. That's 100% typical for debug logs.
