Dataflow Error/Possible Bug: The credentials provided for the PowerBI source are invalid

[mark_carlisle]

I'm building a dataflow that links to other dataflows for and merges or appends those tables where required. The structure of this is shown below. The blue blocks are the data sources, yellow blocks are dataflows that do not use a gateway (i.e. all data sources are cloud based), orange blocks are dataflows that use a on-prem gateway.

The completed data will be in the Surveys dataflow. This all works up until a point, when I get an error. The Surveys dataflow contains the following entities structured in the follow way;

The blue blocks are Linked Entities and have the Enable Load option unticked, the green are entities computed from the linked entities and will have the Enable Load option ticked, these are the entities people will be using in their reports.

The final entity with a red border is the problem. If I untick Enable Load on KPIs and KPIAmendments then the dataflow refresh fails, if I have the Enable Load option on those tables ticked then the dataflow refresh works. Why is this failing when all the other linked entities can have the Enable Load option unticked and the dataflow refreshes fine?

The error I get is;
