Mautic2.2 on-site Sugacrm integration KO

[YannickBiet]

| Bug report? |

Description:

I installed Mautic 2.2.0 on my own server (php7 / debian8 / apache 2.4)
I then configured SugarCRM integration to connect to my Sugar ONDemand instance (sugar entreprise 7.7.1.1)

As soon as I set in my form the action Push to integration the form is broken, the contact is recorded within mautic, but no actions are triggered on the form's action list :

• score not updated
• no assets downloaded
• no integration within my CRM

If a bug:

| Mautic version 2.2.0 |
| PHP version 7.0.11 |

Steps to reproduce:

1. Install Mautic
2. Setup sugarcrm connector (version 7.x using admin account oauth 2.0 access token created inside sugar / authroize app / setup a very basic mapping using email last name + first name)

Log errors:

here's the log trace found in system info :
