If you're able to provide screenshots of the query blocks and the error logs you see in the workflows UI, that will help us troubleshoot. This error comes up when we can't persist the the query block results. A common cause is that there are too many operations running at once. I've seen this happen before with a loop block that was missing an await
statement so the queries were firing off too quickly. If you're testing with complex block logic, I would recommend trying this again with a very simple code block (i.e. return 1 + 2
).
