The error you're encountering, 'RetrieverToolComponent' object has no attribute 'set_event_manager', suggests that the RetrieverToolComponent class does not have a set_event_manager method implemented. This method is likely expected to be present in the component to handle event management, as indicated by the traceback.

To resolve this issue, you can consider the following steps:

1. Check for Method Implementation: Verify if the RetrieverToolComponent class or its parent class CustomComponent has the set_event_manager method implemented. If not, you may need to implement this method in the RetrieverToolComponent class.

2. Implement the Method: If the method is missing, you can implement it similarly to how it's used in other components. The set_event_manager method typically assigns an EventManager instance to an attribute, allowing the component to handle events like logging or sending messages.

   Here's a basic example of how you might implement it:

   def set_event_manager(self, event_manager: EventManager | None = None) -> None:
       self._event_manager = event_manager
   

3. Review Related Code: Ensure that any other parts of the code that interact with RetrieverToolComponent are compatible with this change. This includes checking how the build method and other related methods are implemented.

By implementing the set_event_manager method, you should be able to resolve the AttributeError and allow the RetrieverToolComponent to function as expected.

@edwinjosechittilappilly I notice this issue prevents using agents with tools in the online version. Might you know please when it will be released?

[edwinjosechittilappilly]

This issue is fixed and will be available in upcoming release. We have a release scheduled for this week,mostly today.

did someone try to fix it mannualy like @dosubot suggested? it worked? No you can't just add the method to your Retriever Component -> it errors out when trying to save.

The issue with the RetrieverToolComponent not having a set_event_manager method has been identified and is being addressed by the maintainers. A fix has been implemented and is expected to be included in an upcoming release, which is scheduled for this week. It is recommended to wait for the official release rather than attempting a manual fix, as adding the method manually may lead to further errors when trying to save the component [[id=4640]].
