Thank you for this. Since I couldn't copy the lines from the image, I've included the changes I made below.
New line added at 2796, in Apps Code > Echo Speaks
} catch (ex) {
log.debug "error still exists: getDeviceActivity | Response Exception | Status: (404) | Msg: status code: 404, reason phrase: Not Found"
//jocko: line above added; line below commented
//respExceptionHandler(ex, "getDeviceActivity")
// log.error "getDeviceActivity error: ${ex.message}"
}
This still logs the error since without it, over time, it will be lost from the logs.
