TwitchAPI disconnects every 30 minutes

[iRadEntertainment]

So apparently the client connection cannot stay open forever and it disconnects after some time.

Same issue, but I still need to update gift to the latest build,but it does seem to disconnect (since December) . If I got any valuable debug information I will add it here.

This issue should be renamed: I dug a little more into HTTPClient class to figure out what was wrong.
I was getting the error:
request: Condition "status != STATUS_CONNECTED" is true. Returned: ERR_INVALID_PARAMETER
when using requests from the TwitchAPIConnection.

I believe the problem was related to having a request call while client.get_status() == HTTPClient.STATUS_BODY.

My hacky and NOT IDEAL solution has been to wait to finish polling the body within the request function.

Original code in TwitchAPIConnection:

func poll() -> void:
	client.poll()
	if (client.get_status() == HTTPClient.STATUS_BODY):
		client_response += client.read_response_body_chunk()
	elif (!client_response.is_empty()):
		received_response.emit(client_response.get_string_from_utf8())
		client_response.clear()


func request(method : int, url : String, headers : PackedStringArray, body : String = "") -> Dictionary:
	client.request(method, url, headers, body)
	var response = await(received_response)
	match (client.get_response_code()):
		401:
			id_conn.token_invalid.emit()
			return {}
	return JSON.parse_string(response)

My edits to code in TwitchAPIConnection:

func poll() -> void:
	client.poll()
	if (client.get_status() == HTTPClient.STATUS_BODY):
		client_response += client.read_response_body_chunk()
	elif (!client_response.is_empty()):
		received_response.emit(client_response.get_string_from_utf8())
		client_response.clear()


func request(method : int, url : String, headers : PackedStringArray, body : String = "") -> Dictionary:
	# --- MY HACKED SOLUTION
	while client.get_status() != HTTPClient.STATUS_CONNECTED:
		while client.get_status() == HTTPClient.STATUS_CONNECTING:
			await get_tree().create_timer(0.1).timeout
		if client.get_status() in [HTTPClient.STATUS_DISCONNECTED, HTTPClient.STATUS_CONNECTION_ERROR]:
			client.connect_to_host("https://api.twitch.tv", -1, TLSOptions.client())
		else:
			client.poll()
			if client.get_status() == HTTPClient.STATUS_BODY:
				client_response += client.read_response_body_chunk()
			elif (!client_response.is_empty()):
				received_response.emit(client_response.get_string_from_utf8())
	# --- MY HACKED SOLUTION
	client.request(method, url, headers, body)
	var response = await(received_response)
	match (client.get_response_code()):
		401:
			id_conn.token_invalid.emit()
			return {}
	return JSON.parse_string(response)

I am not confident in my network connection knowledge, so I won't suggest this as a definitive solution. But I hope this can help somehow.
If I have any updates or more errors related to connectivity I'll post them here.
Btw thank you issork for your amazing work!

EDIT: In the original response I used OS.delay_msec(50) which is a blocking thread solution. Not ideal. So I changed it to await get_tree().create_timer(0.1).timeout

Nice work @iRadEntertainment !

I get this as my output currently in debug mode (as spam) :
At: res://addons/gift/gift_node.gd:292:_process() Connecting to Twitch IRC. Reconnecting to Twitch...

So it probably is indeed to do with re-establishing of the connection. Also I have been tinkering with other APIs and the reconnection problem is also found in a few other APIs, if I read their message boards. So perhaps something has changed since last year that breaks some connection codes.

This week I should be able to test a few setups as well, if I can add any fresh findings to this discussion I will. My speciality is not really in networking so lets see how it goes.

Can't seem to use the updated get_tree() code because the current TwitchAPIConnection extends RefCounted which is not a Node. Had to go back to using the blocking sleep, feels bad, but works?

EDIT: I still get eventual disconnects and status -1

Please let me know if this issue is still present. There have been multiple changes to the TwitchAPIConnection since.

Regarding get_tree() - you can always use Engine.get_main_loop() to retrieve the current main SceneTree.
