SAP Business Application Studio : deploy to hana cloud trial HDI container fails

Hello,

I am following this tutorial :

https://developers.sap.com/tutorials/hana-cloud-cap-create-database-cds.html

I am stuck at step 3.9

After binding my project to a HDI container, I try to "deploy" but it fails with this error :
Task 'SAP HANA: Deploy module at /home/user/projects/MyHANAApp/db (MyHANAApp)' has exited with code 1.

As you can see on the screenshot, I tried to deploy 13 times, it just creates an empty Task each time.
