Error while compiling otel_batch_processor

[Andronikus]

Hi 👋

I am using Erlang/OTP 22 and I am following the documentation to add opentelemetry-erlang to my project. I am using rebar3 and I added opentelemetry_exporter and opentelemetry as dependencies of my project.

When I compile the project, it fails to compile otel_batch_processor.erl with the following message.

otel_batch_processor.erl:50: badly formed deprecated attribute {set_exporter,1,[115,101,116,32,116,104,114,111,117,103,104,32,116,104,101,32,111,116,101,108,95,116,114,97,99,101,114,95,112,114,111,118,105,100,101,114,32,105,110,115,116,101,97,100]}

I am using the open telemetry version {<<"opentelemetry">>,<<"1.3.0">>}

Can someone help me to understand what is happening here?
