Possible Solution

Context

I found that the array_pb2 is present at two locations:
ni_measurement_plugin_sdk_service\_internal\stubs\ni\protobuf\types\
ni\protobuf\types\
This might be the issue due to same name.

Your Environment

• OS & Device: Windows
• ni-measurement-plugin-sdk-service version 2.3.1
• InstrumentStudio version 25 Q4
• Python version 3.9.13

@Anmol-Ni @dixonjoel Note that the README.md for the examples dir says:

For best results, use the example measurements corresponding to the version of InstrumentStudio that you are using. Newer examples may demonstrate features that are not available in older versions of InstrumentStudio.

Users of release versions of ni-mesaurement-plugin-sdk-service should be able to use the examples from the zip files without getting this error.

The examples in the main branch are for the next release under development. As you have correctly identified, they are currently broken.

I think the sample_measurement example is broken because it depends on both the new ni-protobuf-types package and the most recently release version of the ni-measurement-plugin-sdk-service package, which both contain the same proto types.

We should uncomment this until the next release, so the examples in the main branch will use the ni-measurement-plugin-sdk-service code from the main branch:

# Uncomment to use prerelease dependencies.
# ni-measurement-plugin-sdk-service = {path = "../../packages/service", develop = true}

Latest version in main runs correctly.
