URL generation via Postman and Rest - The resource cannot be found

Hello,

I am trying to generate a URL via the Rest API by using the Postman collection provided from docuware:

POST request to:
OUR_DOCUWARE_URL/DocuWare/Platform/FileCabinets/111524bd-c059-4807-b380-cb15b62132be/Query/DialogExpressionLink?sortOrder=HAENDLERNUMMER%20Asc&fields=HAENDLERNUMMER&dialogId=02bd3e65-ce44-4351-8b25-43bde1707237

Body content (json):
{
 "Condition":[ {"DBName":"HAENDLERNUMMER", "Value":["19"]}
             ],
 "Operation":"Or"
}

Howerver, when i make the request out of Postman i only get an error page returned: The resource cannot be found.

It seems like the url (with DialogExpressionLink) is not correct? Has it changed? We are using docuware 7.3
Other request are running well (For example a request to OUR_DOCUWARE_URL/DocuWare/Platform/FileCabinets/111524bd-c059-4807-b380-cb15b62132be works quite well)

What can be the problem here?
