Nullable Object must have a value

[Michael-]

Hello,

I'm having issues with refreshing a dataset.  I'm connecting one excel sheet and several sheets (lookup tables) within it then connecting two larger sheets with a few thousand rows.  With all of this data I join and combine them and generate a result set that I then connect to an Athena query with the same schema. 

When I refresh it takes forever and then says it is complete but I'm clearly missing data.

I'm not sure how to upload the error code since it exceeds 20,000 characters.

Here's a snippet:

Unexpected error: Nullable object must have a value.

@Michael- ,

There should be something wrong with Athena query in your model. Actually it's very hard to reproduce this issue on my side. I would suggest you create a support ticket here for further analysis.
