Note: This feature is available in Web Workers.
The read-only WebGLContextEvent.statusMessage property contains additional event status information, or is an empty string if no additional information is available.
The statusMessage property can contain a platform dependent string with details of an event. This can occur, for example, if the webglcontextcreationerror event is fired.
const canvas = document.getElementById("canvas");
const gl = canvas.getContext("webgl");
canvas.addEventListener("webglcontextcreationerror", (e) => {
console.log(
`WebGL context creation failed: ${e.statusMessage || "Unknown error"}`,
);
});
