unable to compile opentelemetry_zipkin

[yatender-oktalk]

I am trying to update opentelemetry_zipkin to {:opentelemetry_zipkin, "~> 1.1"}
but it's giving the following error when I compile it.

===> Analyzing applications...
===> Compiling opentelemetry_zipkin
===> Compiling src/opentelemetry_zipkin.erl failed
src/opentelemetry_zipkin.erl:92:24: field system_time_nano undefined in record event
src/opentelemetry_zipkin.erl:95:81: variable 'Timestamp' is unbound

** (Mix) Could not compile dependency :opentelemetry_zipkin, "/Users/yatendersuman/.asdf/installs/elixir/1.14.2-otp-25/.mix/elixir/1-14/rebar3 bare compile --paths /Users/yatendersuman/codebase/project_name/_build/dev/lib/*/ebin" command failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile opentelemetry_zipkin", update it with "mix deps.update opentelemetry_zipkin" or clean it with "mix deps.clean opentelemetry_zipkin"

i tried cleanup & update as well but it didn't work.
any idea what I might be missing?
Thank you in advance.
