AUR0204: Trying to create a scope with null/undefined binding context

Description

This error occurs when Aurelia tries to create a binding scope but the binding context is null or undefined. This typically indicates a lifecycle/timing issue or a missing view-model/binding context in a composition scenario.

Common Scenarios

• Creating/binding a view before its view-model is available.

• Manually composing a view with an invalid context.

Solutions

• Ensure the component/view-model exists before binding begins.

• For async composition, wait for the promise to resolve before starting/binding.

Troubleshooting

• Check the stack trace for where scope creation is triggered.

• Verify any custom rendering/composition code passes a valid binding context.
