Hi Daniel, Sorry, I missed your comment that you changed test files and could explain why I could not catch your exceptions. But unfortunately, you had to remove it from you repository. Can you make it available for me again please ? Thanks

Hello Aymeric,

I will attach the new files in the morning.

[danielhrisca]

I've uploaded them to the issue in my repo
