Tracing Applet from Smartthings Log to IFTTT

I am getting an error in the Smartthings log, but I cannot seem to find how to identify what applet is causing this issue. The same identifier is appearing in each record with the following message.

Error parsing ifttt payload groovyx.net.http.ResponseParseException: OK

Same here, I cannot find what it is causing, what device? what trigger?
