Have you “[Registered components in AcceleratorModule](https://docs.litium.com/documentation/litium-documentation/dashboard/how-to-create-your-own-widgets_3#Register%20components)” and [built the project](https://docs.litium.com/documentation/architecture/field-framework/creating-a-custom-field-type#Build)?

Is there any error in the Network tab of the DevTools?
