Error bringing in additional datasets/tables to Amazon Quicksight Dataset

I am trying to built out an Amazon Quicksight data set and keep getting an error when bringing in a new table/dataset (I currently have 11 tables/datasets in my model). The error information that I am receiving is not at all informative. I am wondering if anyone has experienced something like this or if there is a known limit on the number of tables/datasets that can be brought into a single data set?
