When an error occurs in technique editor, a notification with a generic message tell us that an error occured, but nothing more, which is a shame since the API return an error message, which most of the time, tell us what goes wrong.
For example, when we try to save a technique that already exist, we have an error notification (See screenshot) :

Error when saving technique: The server had a problem, try again later

But the API provides a clear error message about what happen

"Could not create ncf technique <- Technique name and ID must be unique. 'Toto' already used" 

We should at least be able to display the error message response from the API.
