Connect Bonita to Alfresco repository

Hi, I’m new to Bonita and Alfresco.

I want to upload a file through a form and store it in an Alfresco folder.

So, I created a task with a form where the user would upload a file and the same task has a connector to alfresco 4.2.

When I run the process, and I click the “Soumettre” button in the portal, I get the following error message:
“Erreur lors de la soumission du formulaire.”

Here’s my complete process exported.

Thanks in advance for your help.

I found the solution.
I had a data “file” associated to the whole pool which was not used and it was causing this ambiguous problem…

Hope this could help someone.
