Invalid channel name or instance: 'yyyy'.

Error message

Invalid channel name or instance: 'yyyy'.

Parameters

Channel name or instance (string or object)

Error explanation

This error occurs when you attempt to publish an event using the EventAggregator, but the channel name or instance provided is invalid (e.g., undefined, null, or otherwise not a valid event name or instance). The EventAggregator requires a valid string channel name or a valid instance to publish events.

Common causes

• Attempting to publish an event with an undefined or null channel name.

• Passing an invalid object or value as the event instance.

• Programming errors where the event name or instance is not set correctly before publishing.

How to fix

• Ensure you are passing a valid string as the channel name or a valid instance when calling publish() on the EventAggregator.

• Check your code for places where the event name or instance might be undefined or null.

• Add validation or error handling to ensure only valid events are published.

Debugging tips

• Check the stack trace to see where the invalid publish call was made.

• Search your codebase for all calls to EventAggregator.publish() and verify the arguments.

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