OData Query Service - The exception message is 'Object reference not set to an instance of an object.'.

Hi Technophiles!

The server encountered an error processing the request. The exception message is 'Object reference not set to an instance of an object.'.


If someone have faced this error through browsing the link "http://aoshost:8101/DynamicsAx/Services/ODataQueryService/", the cause could be a query specify on the "Document data sources form" ( Organization Administration > Setup > Document management  ) that doesn't exist anymore.
So, from the form above, delete the queries that no longer exist.

Finally, if you faced problem with the link above, change the AOS server name with the IP address, like http://xxx.xxx.xxx.xxx:8101/DynamicsAx/Services/ODataQueryService/

See you soon!
