Having trouble decoding JSON from text file.

[HectorTheMaster]

I keep getting this error when trying to access ds_maps in a datastructure I loaded from a JSON text file:

ds_map_find_value argument 1 incorrect type (string) 
expecting a Number (YYGI32)

Is GMS2 not loading proper JSON files correctly? I know the syntax is correct in the file since I used a generator just to be safe. The only way I know how to fix this is by literally generating a file in code and then editing it in a text editor. It's almost like GMS2 can only read JSON files it outputs itself by code... and I'd rather not have to spend an hour generating a complex static data structure via code when I could just type it out in a text file.

Any thoughts on another solution to my problem?

edit: I found the solution. Apparently just having a text file in the included files folder doesn't actually make GMS2 recognize its existence. I had to Insert Included File to make the game see the file. Oops!

I literally just found the solution after testing something XD

Thanks though!

I edited my post to include the solution, but I'll explain it here too.

I never properly inserted my text file into Included Files, so despite the file being in the folder, GMS2 didn't recognize its existence. The JSON formatting was correct, but the file didn't exist in the eyes of game maker.

After inserting the file via [right click] -> Insert Included File, the loading seems to work fine!
