AUR3175

Error Message

AUR3175: %s does not appear to be a component or CustomElement recognizable by Aurelia; make sure to use the @customElement decorator for your class if not using conventions.

Description

This error occurs when a lazy import resolves to something that the router cannot treat as a component/custom element (for example, the module does not export a custom element, or the class is missing @customElement and conventions are not enabled).

Solutions

• Ensure the imported module exports a custom element view-model (or definition) that Aurelia can recognize.

• Add @customElement(...) if you are not relying on conventions.

Troubleshooting

• Inspect what the import resolves to (the %s value) and confirm it’s the expected component.

• Ensure you’re importing the correct module/export.
