Create Map Data Structure for Fast Lookup

Howdy all,

I've been trying for a few days to create a map like data structure so that I can immediately lookup a certain data property. The idea would be to have a map that looks like the following while being able to look up each individual entry by name :

{
    "body": [
        {
            "file.csv": "90275834"
        },
        {
            "file1.csv": "362251262"
        },
        {
            "file2.csv": "129143557"
        },
        {
            "file3.csv": "112120"
        }
   ]
}
 
So far I've been able to populate an array with mapped values as I've just shown,
but have had issues in generating a dynamic map structure within a single object. I wanted
to create an empty object, and then dynamically populate it with each array entry using 
a 'set Variable' and writing out a function : 
 
setProperty(variables('fileMap'), first(keys(items('Apply_to_each_1'))), items('Apply_to_each_1')[first(keys(items('Apply_to_each_1')))])
 
, but this gets a "self reference not supported" error. Does anyone have any ideas on how to do this?
