	my_http_request.request_completed.connect(self._my_http_request_completed)
	
	_my_http_request()

	my_json.parse(my_body.get_string_from_utf8())
	var my_response = my_json.get_data()
	print(my_response["message"])

No syntax errors.

but a runtime error.

Connect the signal like this:

my_http_request.connect("request_completed", self, "_my_http_request_completed")

Connecting signals in Godot 3 and Godot 4 are difference.

Thank you.
I appreciate it.

The runtime error

Invalid get index ‘request_completed’ (on base: ‘HTTPRequest’)

is gone.

But the runtime error

Invalid call. Nonexistent function ‘new’ in base ‘_JSON’.

is displayed on the line

var my_json = JSON.new().

new function not exist in JSON, it will JSON.parse(your_data), check its docs
