2025-06-13 02:11:40.256  INFO 22860 --- -uplink-thread-1] c.celonis.uplink.manager.UplinkManager   : Uplink could not connect: 'Error while extracting response for type pclass cloud.celonis.uplink.manager.UplinkDataWrapper] and content type papplication/json;charset=UTF-8]'

I'm sorry to know that you're facing this issue. It appears that the Celonis Extractor Server is failing to connect to your Redshift database, indicated by an "Error while extracting response" message. This typically points to an issue with how the Extractor Server is receiving or interpreting the data coming back from Redshift, even if the connection itself seems to initiate. To resolve this, first, meticulously verify all Redshift connection details, including credentials and network accessibility (check firewalls or security groups). Then, ensure the correct JDBC driver for Redshift is properly installed and recognized by your Extractor Server, as an outdated or missing driver can cause response parsing issues. Finally, examine the Extractor Server's detailed logs for more specific error codes or messages, as the generic "Error while extracting response" often masks underlying problems like authentication failures or unexpected data formats from Redshift. Hope this helps🙂
