Key error 'company' with account_fr_chorus module

Hello !
I’m trying to test the usage of the account_fr_chorus module.

I followed all the tutorials to use Chorus Pro qualification service, creating an account, generating test data, creating an account on AIFE to link Chorus with a PISTE app, creating a technical account. Then I filled the Chorus section in the Financial configuration of Tryton with the login and password of the technical account, I installed the edocument_uncefact module to be able to choose CII as Chorus Syntax. I checked the Chorus Pro option for all the parties I registered and I filled in their SIRET. Then I created a customer invoice and I posted it, which has generated a Chorus invoice.

The problem is that the Chorus invoice is apparently not sent to Chorus Pro. I went on the Administration → Scheduler → Actions menu, I selected the “Send invoices to Chorus” method, and when I click on the “Run once” button, I get the following error :

Has someone already experienced this error ? Do you have some tutorial to help me finish to set up the account_fr_chorus module ?
Thanks for help !

PS : here are the tutorials I followed for the Chorus and AIFE part :
