If you have a customer who gets an error and cannot recreate it yourself, you can get a “copy” of the customer's network stack and import it into your own browser for further troubleshooting, without getting on a call with the customer.

 

Step 1:

Get the HAR request from the customer.

Step 2:

Open a new window in Chrome and bring up the developer tool (F12)

Click the import button and select the HAR file.

 

Step 3:

Troubleshoot the call stack as you normally would.

 

Tips:

Find the call that is giving trouble and extract the X-Activity-Id from the Response header and open it directly in the logs to get the whole call.

Note the ID will be something like this:00-49ba5e1a5c3948458c10eb11c08db4a8-8a0064bb02af804f-01

and you only need the 49ba5e1a5c3948458c10eb11c08db4a8 part of the ID. (Trace ID).

the 2th part 8a0064bb02af804f is the span ID

Enter the Trace ID in the log search:
