Incorrect argument passing in Ant?

Question

CVS

There is code:
Ant script:

<property name="propertyName" value="<корень папки>/folderMain"/>

<target name="targetName">

       <exec dir="<путь до папки, в которой находится someFile.js>" executable="${env.NODEPATH}\node" output="<путь до txt-файла>">
           <arg line="someFile.js"/>
           <arg line="${propertyName}/ru/rootNew/folderNew"/>
       </exec>

</target>

js code (someFile.js):

var dir1 = path.resolve(process.argv[2]);
var dir2 = path.resolve(process.argv[3]);

<остальной код>

When executing the code in a txt file, the output is:

Error: ENOENT, no such file or directory '<путь до папки, в которой находится someFile.js>\null\rootNew\folderNew'

If you specify the path in target in the second argument without using properties / variables, then the code works correctly.
Please tell me what is the reason for the error?
UPD:
I don't know what exactly happened, but now everything works.
Issue resolved.
