Nvmsgbroker errors when using kafka deepsteam python

I’m writing code in python
The task is to save frames and send some information to kafka. I have created a pipeline that you can see in the image, but I get an error:

0:00:08.781040064 2684807      0x4461f20 WARN             nvmsgbroker gstnvmsgbroker.cpp:375:legacy_gst_nvmsgbroker_start:<nvmsg-broker> error: No protocol adaptor library provided

I will also leave the full log below. Please note, if I run the same code without the kafka module, it runs and works (though with some warnings)

nvmsgbroker plugin is opensource. from the error, proto-lib is not set. take deepstream-test4 for example, the following parameters are used to pass kafka information. please refer to readme.
-p /opt/nvidia/deepstream/deepstream/lib/libnvds_kafka_proto.so --conn-str="localhost;9092"

[romefellsosad]

yes, you’re right, I initialized the proto_lib and conn_str variables incorrectly

Sorry for the late reply, Is this still an DeepStream issue to support? Thanks!
