Mailjet integration - Contact List is empty

Hello,

We bought Pabbly Connect to link our Elementor Form to Mailjet. Everything is fine with Elementor integration but not for Mailjet. The contact list is empty even if our client have multiple contact list. (see attached file)
Wy tried to click on the refresh button but it stay empty, we tried to write our contact list name but it says there is no contact list. Since the Contact List is Required, we can't save our integration.

Any ideas ?

Thank you

My mistake, the problem was from my side. My client sent me a Subaccounts API and not the main API, that's why it didn't work :)
