Message
A query on a Buffer source step has timed out as it is returning results.
Cause
When fetching large amounts of data from a Buffer source the data is fetched in batches in the background. The query will take longer to process as the amount of Buffer data increases. When the max time limit (2 minutes) for getting the next batch is reached this error will occur.
Resolution
Make sure you have created Buffer indexes that satisfy your query (account for the query, the sort and any joins you may have)
Consider limiting the amount of data being returned
Simplify your Buffer query and filter the response within the flow
