描述

What happened?

When i define a primitive use asynchronous: true like code below

        const primitive = new Cesium.Primitive({
            geometryInstances: instance,
            appearance: new Cesium.PerInstanceColorAppearance({
                flat: true,
                translucent: true,
                renderState: {
                    lineWidth: Math.min(2.0, viewer.scene.maximumAliasedLineWidth)
                }
            }),
            asynchronous: true,
            releaseGeometryInstances: true
        })

But browser report bug: DeveloperError: Must define either _workerName or _workerPath for asynchronous geometry. ssandcastle_url How or Where to define the _workerName or _workerPath var ?

研究方向
The error 'Must define either workerName or workerPath for asynchronous geometry' occurs when setting asynchronous:true on a Primitive. The user provides a Sandcastle reproduction link. To resolve, investigate the Primitive source code to understand default values for workerName and workerPath, or check if documentation examples set these. Look for any existing issues or PRs discussing async geometry requirements.
