The GPUUncapturedErrorEvent interface of the WebGPU API is the event object type for the GPUDevice uncapturederror event, used for telemetry and to report unexpected errors.

Known error cases should be handled using pushErrorScope() and popErrorScope().

GPUUncapturedErrorEvent() Experimental

Creates a new GPUUncapturedErrorEvent object instance.

Inherits properties from its parent, Event.

error Experimental Read only

A GPUError object instance providing access to the details of the error.

You could use something like the following as a global mechanism to pick up any errors that aren't handled by error scopes and capture them.

// ...

device.addEventListener("uncapturederror", (event) => {
  // Re-surface the error
  console.error("A WebGPU error was not captured:", event.error.message);
  reportErrorToServer({
    type: event.error.constructor.name,
    message: event.error.message,
  });
});
