Project related invoice line distribution cannot be created

We need help in an issue about entering project related invoice line distribution:

when we enter invoice line amount, project/task numbers, expenditure type and organization, we click "Distribution" button, it should pull the default account for project accounting and create distribution

But we noticed that for some project/task/expenditure type/organization combinations, the creation of invoice line distribution failed, we see following errors.

If we use the same project/task with different expenditure type, the invoice line distribution can be created with the default account successfully

We have checked workflow for invoice line account generator, it is in valid status. we also check related accounting dates, project/task budget dates, status, etc.. they are all in valid status or open...
