Issue in accessing custom ui_resources.xml

I am trying to add XML file for Custom Error messages which will be used in JavaScript in my application. Location where I have added ui_resources.xml is - \Aras_Dev14\Innovator\Client\Solutions\DR\xml
However , I am not able to access any value in this XML. If I access XML from any other folder I can do that. So I believe this issue is related to some kind of folder mapping that needs to be done in ARAS.
can you please help me with this?
