When Creating a Custom Feature Matching Node The Output Does Not Have "feature_files"
A clear and concise description of what the problem is.
So when making a custom feature matching node in Meshroom the output does not have tags that Meshroom recognizes, how do I fix this?

What settings do you have in the node?

Hello. Here is the issue: We are trying to access all of this data through meshroom from an external Python add-on. We are not sure how to access the data from here

Take a look at this two repository for reference on implementing Python nodes:
https://github.com/PIX3LFLUX/MeshroomDFM --> has good developer documentation
https://github.com/MrClock8163/MeshroomGCPMarkerAdditions --> is probably the right approach for you

Custom Nodes

You can create custom nodes in python and make them available in Meshroom
using the MESHROOM_NODES_PATH environment variable.
Here is an example to launch a Blender rendering from Meshroom.
In a standard precompiled version of Meshroom, you can also directly add
custom nodes in lib/meshroom/nodes. To be recognized by Meshroom,
a custom folder with nodes should be a Python module (an init.py file is needed).

Also there is some work in progress for support of unknown image detector/descriptor types #2252
