Error when generating documentation against a Dataverse solution

[benjy-evans]

When attempting to generate the markdown version of documentation for a Dataverse solution, I get a error "sequence contains no elements".
To Reproduce
Steps to reproduce the behavior:

1. download solution from Dataverse, which includes tables that do not have elements in the columns section (I don't have any custom columns on the aaduser table, just relationships as an example)
2. load up PowerDocu
3. set output to markdown
4. start the process

Expected behavior
The documentation to be generated without error

I get the same error.

But if I clone the main branch and run it locally in Visual Studio, the error doesn't happen. So must be something wrong with the build used for that Release maybe?
