Recurring 5520 errors when getting supplier invoices

[ErikW]

At least 8 of our customers are experiencing recurring and intermittent 5520 IPPExceptions in their integrations for supplier invoices when getting supplier invoices using the endpoint: /controller/api/v1/supplierInvoice/{documentType}/{invoiceNumber}. 

The problem seems to come and go and cannot really be replicated but seems to have been ramping up during the day today. These integrations have existed for between 3 months and 2 years and each integration uses Visma Connect for authentication.

Hi!

How long have the customers been experiencing these exceptions? Did this start today?

There are currently some problems with Visma Net ERP. However, I’m not sure if these issues are related. https://status.visma.com/incidents/2htg2y36gs2p

The issue seems to have mainly started and escalated today, but we do have some examples up to a week ago.

Has this problem been resolved, or do your customers still experience IPPExceptions?
