While going through the request/responses for one of the synthetic monitoring script, the status for a request was mentioned as “400 Service Worker Fallback Required”. After this error, there was another instance of the same request that was successful with 200 response code. To understand if this is happening for production users, browser monitoring was examined. The same ajax request was shown as having Network error under the “Status code Excluding 200s” section. Can you please help with the below?
- The reason for “400 Service Worker Fallback Required” error in Synthetics script
- More details on Network error under the “Status code Excluding 200s” section from the browser monitoring
- Are the above two related, as the synthetic script has been running continuously as part of our monitoring?
