so when i try to do :JSONDecode on a json string (that i am aware is huge), it errors Script timeout: exhausted allowed execution time?

function:

local function requestPixels(parameters: {[string]: any}): pixelsData
	local url = BASE_URL

	for parameter, v in parameters or {} do
		url ..= `?{parameter}={v}`
	end

	return HttpService:JSONDecode( -- error here
		HttpService:GetAsync(url) or '{}' -- not here
	)
end

You might want to use Parallel Luau then, though I’m can’t guarantee it will work.

i do use parallel luau in the background (only for rendering and also in the backend), but how do i parallel luau when the error is coming from :JSONDecode? (which is built-in)

The above error occurs when you use a loop without wait. Just add a task.wait() or wait() in the loops and you’ll be good to go!

its not the loop, its coming from the :JSONDecode, not anywhere else

What are the params your sending? Are they being unpacked via a table or something into the function? (Edit: Saw your using a table, just tell me what params your using)

It’s still erroring despite not entering the parameters? Print the url out after and before the for loop. Tell me what you get.

local function requestPixels(parameters: {[string]: any}): pixelsData
	local url = BASE_URL
    print(url, "Before")
	for parameter, v in parameters or {} do
		url ..= `?{parameter}={v}`
	end
    print(url, "After")
	return HttpService:JSONDecode( -- error here
		HttpService:GetAsync(url) or '{}' -- not here
	)
end

Maybe your spamming the requestpixels function? try lowering the amount.

they print out the same url and i don’t think a loop concenating a string would produce that error

no, it will be only called once

sorry for the late response :sweat_smile:
(keep in mind the backend server takes quite some time to return a response (its short enough to not produce a timedout) so it would take time for me to test your solutions)

i managed to store the data in a json file; the size says its 2,15,019 KB? what does that mean
image
the shortest and smallest one is 3870 KB

i turned it to a grayscale and now its 2,43,542 KB, i don’t know what that means, but it WORKS with grayscale
