The uncapturederror event of the GPUDevice interface is fired when an error is thrown that has not been observed by a GPU error scope, to provide a way to report unexpected errors.

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

Syntax

Use the event name in methods like addEventListener(), or set an event handler property.

js
addEventListener("uncapturederror", (event) => {});

onuncapturederror = (event) => {};

Event type

An GPUUncapturedErrorEvent. Inherits from Event.

Event GPUUncapturedErrorEvent

Examples

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.

js
device.addEventListener("uncapturederror", (event) => {
  // Re-surface the error.
  console.error("A WebGPU error was not captured:", event.error);

  reportErrorToServer({
    type: event.error.constructor.name,
    message: event.error.message,
  });
});
