Hi team,
I've been seeing continual failures of a Stitch Salesforce Marketing Cloud integration since Friday (January 9th). It fails on the ListSend endpoint with the error "tap - ERROR Giving up sync_data(...) after 5 tries (socket.timeout: The read operation timed out)." I've tried running it at different times of the day, with the same result.
From reviewing the logs, the integration initially makes requests to this endpoint without issue. So, Stitch is successfully authenticating and calling ListSend. However, after doing so a few times, Salesforce does not return a response in the socket timeout window. After 5 retries, the tap gives up and the integration fails. See the footer for example logs.
Do you have any suggestions about how to resolve this? I talked with Stitch support in some detail. They mentioned on the Stitch-created workflows, they can increase the socket timeout values. We also noticed there were some fairly recent changes here.
Thank you!
Andrew
