DataSourceError: Analysis Services: The Auto Exist Operation is exceeding the permitted memory limit and is being canceled

I am trying to import a Tabular Model into Power BI. If I load in everything except for the date tables, it works fine. If add in a date table, and a fact table, I get the error DataSourceError: Analysis Services: The Auto Exist Operation is exceeding the permitted memory limit and is being canceled. I saw this error in community.powerbi.com but I didn't see a resolution for it. Can anyone tell me what I can do to resolve this error?
