The below error indicates that the server dataflow was trying to communicate with did not respond back before the dataflow connection timeout (60 seconds) was reached.

 "errorMessage": "ESOCKETTIMEDOUT: Read timed out waiting for server to respond with data."

The most likely occurrence of this will be when making requests to the iFormBuilder API, as the connection timeout limit is 300 seconds. When this error occurs, you should expect dataflow to retry the request, which may result in duplicate results being processed.

To remedy this error, try modifying your request to send (POST) or return (GET) less data, and allow the iFormBuilder API to respond within the dataflow timeout limit.

If you dataflow is sending requests to services other than iFormBuilder, you should work with those providers to determine their connection timeout limits and adjust your requests to complete within those boundaries.
