Hello! I am attempting to add azure opentelemetry to my application that I am packaging with pants. I am following this help article from microsoft. And also this github info. When I run my application via the

pants run

command, I can get the application working with this new library. When I package it into a .pex and then try to run the .pex directly, I get an error. All I'm basically adding in the code is:

from azure.monitor.opentelemetry import configure_azure_monitor    
configure_azure_monitor(
        logger_name="app",
    )

and adding

azure-monitor-opentelemetry==1.6.*

to the reqs file. Here is the error I am getting with the .pex file:

File "/<MY_HOME_DIR>/Library/Caches/pex/unzipped_pexes/4385a4cf921d3dcc4d7b10750fc92a7f3daee3eb/<SNIP>/manage.py", line 4, in <module>

    from azure.core.tracing.ext.opentelemetry_span import OpenTelemetrySpan
ModuleNotFoundError: No module named 'azure.core.tracing.ext.opentelemetry_span'

Now in the working version via

pants run

if I remove proper configuration I can get it to throw an error so we can look at the difference in the library references:

    env_cs = self._parse_connection_string(os.getenv("APPLICATIONINSIGHTS_CONNECTION_STRING"))
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    raise ValueError("Invalid connection string") from exc
ValueError: Invalid connection string

I am suspicious it has something to do with how the modules are mapped differently when ran from pants run, vs pants package, and have played around with

module_mapping
