Debug API errors?

[Gert-Jan van der Kamp]

Hi, 

I'm getting a 500 error when trying to create a PurchaseOrder, is there any way I can see more details for this VismaId like with the Connect debugger? This doesn't provide much detail how to fix the error. 

Error: HTTP 500 : InternalServerError

{"message":"VismaId: ed8061a0-eda8-4b19-8e8e-29177a5f5d7b. Error creating purchaseOrder. Object reference not set to an instance of an object."}
