It would be nice to explain what you meant in this place. IB cannot throw any errors, because it is a data structure.
> As I understand it, you need to register something in the settings of the infoblock?
Of course not, again because it's a data structure. You need to deal with the settings of the component that processes the request and routing. There is no information about this in your question.
From here:
1 Which page (at which URL) gives you 404? What should she give in your opinion?
2 How is the routing configured for this URL?
3 Which script handles this URL? What component? What are the settings for this component?
