I bealive The Azure Cost Management by HTTP Template

I believe that template Azure Cost Management by HTTP has a construction defect.

The monthly cost items only capture the value of the first day of the month, instead of the monthly cost itself.

I believe that this is due to the second pre-processing of these items.

Instead of using the "sum" function to add up all the values ​​for that month, it uses the "first" function, which always returns the first value in the array.

Above has a example of how it works for me.
