JSON parsing error about a missing ':', even though everything is there!

Hi, I'm currently working on a dialog box,

Here is my exact error message:

call: Error parsing JSON at line 1: Expected ':'

Here is my exact Debugger message:

Assertion failed: Dialog not found ( obviously this means it wasn't successful in parsing my JSON file )

I am following a youtube tutorial [

I have recreated my dialog box almost 3 times now, I have tried following the video and copying/pasting the text as well; however I always hit the same road block.

Here is my code:

extends ColorRect

export var dialogPath = ""
export(float) var textSpeed = 0.05
 
var dialog
 
var phraseNum = 0
var finished = false
 
func _ready():
	$Timer.wait_time = textSpeed
	dialog = getDialog()
	assert(dialog, "Dialog not found")
	nextPhrase()
 
func _process(_delta):
	$Indicator.visible = finished
	if Input.is_action_just_pressed("ui_accept"):
		if finished:
			nextPhrase()
		else:
			$Text.visible_characters = len($Text.text)
 
func getDialog() -> Array:
	var f = File.new()
	assert(f.file_exists(dialogPath), "File path does not exist")
	
	f.open(dialogPath, File.READ)
	var json = f.get_as_text()
	
	var output = parse_json(json)
	
	if typeof(output) == TYPE_ARRAY:
		return output
	else:
		return []
 
func nextPhrase() -> void:
	if phraseNum >= len(dialog):
		queue_free()
		return
	
	finished = false
	
	$Name.bbcode_text = dialog[phraseNum]["Name"]
	$Text.bbcode_text = dialog[phraseNum]["Text"]
	
	$Text.visible_characters = 0
	
  
	while $Text.visible_characters < len($Text.text):
		$Text.visible_characters += 1
		
		$Timer.start()
		yield($Timer, "timeout")
	
	finished = true
	phraseNum += 1
	return

Any help is much appreciated, thank you!
