{"ProjectID":"'Project' cannot be empty."}

[SpendControl]

One of our clients is encountering the following error: "Error creating supplierInvoice. Error: Inserting 'Supplier transactions' record raised at least one error. Please review the errors. {"ProjectID":"'Project' cannot be empty."}."

This issue occurs when creating a supplier invoice through the API of which every line has a project set. However, the error persists despite this.

We are unable to pinpoint the root cause of the issue in this scenario.
