If your events aren’t being sent to the server there are a few things that you can try to diagnose the issue.

Update Your Client #

Please make sure that you are using the latest version of the client.

Ensure the Queue has Time to Process #

If you are using Exceptionless in a scenario where an event is submitted and the process is immediately terminated, then you will need to make sure that the queue is processed before the application ends. Please note that the client will try to do this automatically.

Events are queued and sent in the background, if the application isn’t running then the events cannot be sent. You can manually force the queue to be processed by calling the following line of code before before the process ends:

import { Exceptionless } from "@exceptionless/browser";
await Exceptionless.processQueue();

This will cause the event queue to be processed asynchronously and the events to be reported. If this doesn’t solve the issue then please enable client logging and send us the log file. You can also attempt to pass true to process(true) to try and process the queue synchronously. Please note that sending synchronously depends on specific api's that may not be available, so it may not send synchronously.

Enable Client Logging #

The Exceptionless client can be configured to write diagnostic messages to the console to help diagnose any issues with the client.

import { Exceptionless } from "@exceptionless/browser";

await Exceptionless.startup(c => {

Check Your API Key #

By design, an invalid API key provided to the Exceptionless client is not going to crash your application. Be sure to check the log outputs as this information will tell you if you have provided an invalid key.

Debugging Source Code #

You can also debug the Exceptionless source code by using the unmagnified version and set breakpoints in your browsers developer tools.
