Using Invoke-ProcessASDatabase

I am trying to use the Invoke-ProcessASDatabase cmdlet for the SqlServer module.

Setup: I have a server setup with SQL 2016 installed with both SQL and SSAS installed. I have 2 Multidimensional databases that I would like to process using the Invoke-ProcessASDatabase cmdlet.

Problem: I get an error that the database does not exist on the server. I am able to browse to it using both PowerShell and Management Studio. I am even able to use the Invoke-ProcessCube on the cube within the database without error. I am also able to process dimensions within the database without error. I am at a complete loss as to why this is happening. Has anyone experienced this before? How did you resolve it?

tldr: I am having some problems with processing an Analysis Services database with the SQLServer module. Any help with the Invoke-ProcessASDatabase saying that the database does not exist?
