This needs its own environment. The environment in use (bluesky_2022_3) has some problems importing spec2nexus:

Confirmed that problem is local to the environment by creating test environment: micromamba create -n s2n -c conda-forge spec2nexus

This is not a problem with a new environment setup: https://github.com/BCDA-APS/use_bluesky/blob/main/install/environment_2023_1.yml
