OData - Expand on empty list error

(3) ShareShare
ReportReport
Posted on by 7
Hi!

We're using an OData API and trying to use $expand to get data from VendorInvoiceHeaders and VendorInvoiceLines.

Here's an example of the query we're using:

/data/VendorInvoiceHeaders?cross-company=true&$expand=VendorInvoiceLine

We noticed that when Vendor Invoice Header doesn't have any matching Vendor Invoice Lines, the query fails with a very generic error. Is it a known limitation of $expand? Is there a way to avoid this?

 

This is the FO version we're using

Installed product version : 10.0.44 (10.0.2263.26)
Installed platform version : Update68 (7.0.7606.56)
