I am joining 4 datasets together. I have a base/core dataset, which then has 3 distinct joins to 3 other datasets. Each dataset is fine individually, and I can view the datasets in preview mode. However, I am getting ’ INTERNAL_SERVICE_ERROR’ when trying to build/refresh the joined dataset.

If I remove any of the 3 joining datasets, it works OK.

My suspicion is that there is an unpublished timeout happening somewhere. Can anyone shed any light?

Hi @stuart, thank you so much for reaching out and sharing your concerns.

The ‘INTERNAL_SERVICE_ERROR’ is a generic error message and we will need additional information to root cause this particular issue. Could you please cut us a ticket and will further investigate?

Thanks Dev. Unfortuately it would cost me $29 to access AWS support. I will try building it in something else.
