JsonConfig | simple configuration library using JSON and C | Configuration Management library

I'm really new to Javascript. So please bear with my garbage coding but I do not know what this error means and have spent really long trying to solve this. I am using Replit right now but I have also tried it on Visual Studio which gives the same error. Please help, I have no idea what to do!

Whenever I try to run my script it keeps erroring with this:

My issue is

1. I want to be able to loop over each server and within that loop, loop over UsageData
2. My current loop gives me an error about ranging over assets not sure why
3. I cant access assets.Server.UsageData

Here is my code : https://go.dev/play/p/ttNVW5_Q4Ys

I have this table:

I'm trying to write a grammar for a DSL of mine using antlr4. In essence I'm trying to create a DSL for describing function applications in a tree structure.

Currently, I'm failing at creating the correct grammar (or using the visitor in C# correctly) for parsing expressions like

I'm currently trying to create a class and subclasses that encapsulate various configuration aspects (provided in json) for a data pipeline; I'm still very much learning scala as well. I'm using the Play framework library in order to parse the json string input - https://www.playframework.com/documentation/2.8.x/ScalaJson

I have some code that currently works, but there are several aspects of it that feel wrong, and this does not feel like the correct approach.

The workflow for the application needs to take a json string, parse and validate it against various similar but slightly different structures, and then make the values accessible for other bits of downstream processing (e.g. if the file type is a csv file, set some config thus, if it's a json file do this instead); but it's important to note that this is a dynamic process. This seemed to me to be a perfect use case for case classes, but I have a feeling I've misunderstood their use.

So I have a sealed (in order to make sure that all matches are known) abstract class FileConfig, and currently two subclasses, DelimitedConfig and JsonConfig. The DelimitedConfig class also makes use of an additional case class DelimitedFileTypeDetails, which is essentially the main difference between the two at this point, but there will be other deviations added as I continue; and I also have companion objects for all three classes in order to take advantage of the play framework format method:

I am getting an error when using a custom wrapper for MSAL 2.0

Im currently trying to learn to get JSON value from a website which has a script that within JSON inside it which im trying to get with regex.

For now I have tried to do: jsonConfig":\s*.*} which does find a match but does not group it (Which means I cannot get the values to later on parse it with json.loads which I will show at the very bottom of this thread)

Logic of service: fetch data from api and set to properties. After that I call props on blazor client. Service:

I'm sure someone's answered something similar before, but those posts seem to have been lost amongst more popular questions about global variables and loops.

What I'm trying to do is write a loop to step through the Google Analytics API, pulling out data one day at a time. I'm sure there are already some packages that do this but it's somewhat of a learning experience for me.

Where I'm getting stuck is that my loop seems to be progressing the correct number of days however the actual request being sent to the GA Reporting API (V4) isn't updating with the global variable, even though a simple print() seems to indicate it does update.

Here's my code:
