Customer invoice POST returns "Object reference not set to an instance of an object.."

[KonsultVn]

Hi! 

We're once again having problems creating a specific customer invoice where we get back a message that is difficult to interpret in the form of {"message":"VismaId: 31e7c153-86a7-4d17-8568-7d2ca5b233f4. Object reference not set to an instance of an object."}

Could you please help us in this case as soon as possible as well as look into handling this error in a better way?

Hi,

I tried this but we still get the same problem

"message": "VismaId: cf5e5143-a594-47a5-8562-9a9b163ed234. Object reference not set to an instance of an object."

We need to import this invoice into Visma as quickly as possible.

Hi,

The issue most likely lies with the customer missing some field. We would recommend posting something else to this customer/create a invoice in the UI with this customer to see if there is any errors that are thrown.

The lines seem fine but are dependant on the endcustomers settings.

Thanks! I tried linking the customer to a new invoice directly in the UI and received a more detailed error regarding an invalid zip code. It would be greatly appreciated if in the future you could get this error message out rather than the current "Object reference not set to an instance of an object.".

It would have made it a lot easier for us in troubleshooting.
