Invalid channel name or type: yyyy.

Error message

Invalid channel name or type: yyyy.

Parameters

Channel name or type (string or constructor)

Error explanation

This error occurs when you attempt to subscribe to an event in the EventAggregator using an invalid channel name (such as undefined, null, or an invalid type). The EventAggregator expects a valid string channel name or a constructor function for message types.

Common causes

• Passing undefined, null, or an invalid value as the channel or type to subscribe() or subscribeOnce().

• Typo or incorrect variable used for the channel name or type.

• Attempting to subscribe before the channel or type is defined or available.

How to fix

• Ensure you are passing a valid string or constructor as the channel or type when subscribing.

• Double-check for typos or incorrect variables in your subscription code.

• Make sure the channel or type is defined and available before subscribing.

Debugging tips

• Check the stack trace to see where the invalid subscription was attempted.

• Search your codebase for all calls to subscribe() and subscribeOnce() in the EventAggregator.

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