channel selection missing

[khintz]

We have been dealing figuring out why we cant select channels when using observation type satem. To test I built a container.

To make the installation succeed I had to update the class package from 7.3-20 to 7.3-22. See diff here @ewhelan found the following info:

The install.packages() function will ignore your version argument, so you'll get the latest version, 7.3-22. 
Version 7.3-20 is not compatible with R 4.3.x, because the Sint and related definitions have been dropped.
So if you want to install 7.3-20, you'll need to use an older version of R.

I made a containerfile to make an image to use with podman (attached at the end of this issue). Be aware that I tried two different ways to run obsmon:

1. As standalone running the obsmon script: CMD ["obsmon/obsmon"]
2. Through a shiny-server: CMD ["/usr/bin/shiny-server"]

With option 1, we are able to select channels. With option 2 we are not (no channels show up). Our temporary solution, however not ideal, will be to run without the shiny server and force the container to restart if it fails.

Any good guess why this happens?

Recipe for creating and running the image:

podman build -t obsmon -f rocky_obsmon.Containerfile
podman run -d  -v /obsmondata/:/obsmondata/ --net=host --name obsmon localhost/obsmon:latest

Channels are there apparently. Just not possible to select them when running through a shiny-server.

It seems one of the missing pieces was the package pmisc. Installing that made both channel selection work and made the app more stable. The image we ended up using was the following (still updating the class package from 7.3-20 to 7.3-22):
