Issue with Fortnox / invoices routes QueryTool itgenfnx068

[sda]

It seems some of the endpoints in the /invoices/ objects for Fortnox connector have an issue resulting in an error while talking with fortnox API.

Query Tool 25.0.95
Error: itgenfnx068
Message:

So far concerned endpoints are:

• invoices.InvoiceByDocumentNumber
• invoices.InvoiceLinesByDocumentNumber

invoices.invoices works fine.

It seems the error resolved by itself this morning: it is possible to fetch the endpoint without 401.

Note that a re-authentication process has occurred when launching Query Tool. It creates some difficulties since Fortnox is not multicompany, and we don’t know for which company the auth flow is applied for when 2 or more Fortnox databases are defined in the same connection in settings.xml. A separate ticket will be filled.
