Hi,
I am getting the following error while creating cohort through atlas interface. Any suggestions on what can be potential error?

Hi, I have the same problem.

I use 1K Synpuf and necessary vocabularies. I can see Atlas properly gives data statistics report on Report dashbaord. However It seems that whenever we try to save a new cohort, it reports an error.

I tried the same cohort definition at demo server of Atlas https://atlas-demo.ohdsi.org/, and confirmed it was successful. So cohort definition itself should be working. Something wrong in Java processing…
