GPUDevice: uncapturederror event
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Note: This feature is available in Web Workers.
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.
addEventListener("uncapturederror", (event) => { })
onuncapturederror = (event) => { }
Event type
A GPUUncapturedErrorEvent. Inherits from Event.
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.
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,
});
});
