Encoding error while sending a batch of spans

[vlatkapavisic]

Hi, in my Rails app I'm using signalfx-ruby-tracing gem which is using jaeger-client-ruby. I'm getting this error:
ERROR -- : Failure while sending a batch of spans: "\x81" from ASCII-8BIT to UTF-8
which comes from this part of code.

Do you have a clue what might be the reason and what is the severity of the error? Thank you!

I realised it's tied to https://github.com/opentracing-contrib/ruby-redis-instrumentation.

Hi, the maintainers of the gem mentioned above told me the issue comes from Jaeger. Do you have some information about it? Thank you!
