Invalid resolver, null/undefined returned from the static register method.

Error message

Invalid resolver, null/undefined returned from the static register method.

Error explanation

This error occurs when a static register method on a resource or class returns null or undefined instead of a valid resolver. The DI container expects the register method to return a proper resolver object so it can manage the dependency.

Common causes

• The static register method does not return anything or returns null/undefined.

• There is a bug or missing return statement in a custom resource or plugin's register method.

• A plugin or library is not implementing the register method correctly.

How to fix

• Ensure that all static register methods return a valid resolver object.

• Double-check custom resources, plugins, or libraries for correct implementation of the register method.

• Add appropriate return statements to all register methods.

Debugging tips

• Check the stack trace to see which register method caused the error.

• Search your codebase for all static register methods and verify their return values.

• If using plugins, try disabling them one at a time to isolate the source.

Possible solutions

Check the static register method on the resource/type referenced in the stack trace, and ensure it returns a valid resolver/registration.

Please also note that this error could be caused by a plugin and not your application. After ruling out that the error is not being caused by your code, try removing any registered plugins one at a time to see if the error resolves itself.
