Sankaku suddenly stopped downloading

[UpscaleAnon]

It worked completely fine until about 40 minutes ago where gallery-dl just spits out this error:

Everything works fine in my browser and it's failing previously downloaded images so it's not image specific or anything.
I was on version 1.28.4 and updated just now to 1.28.5 but that changed nothing.

hmm, i thought that i was rate limited but it seems it's not just me, probably just a site change

i can retrive the file url from the api just fine: https://capi-v2.sankakucomplex.com/posts?lang=en&page=1&limit=1&tags=id_range%3ALbaWXbvG2ro so it shouldn't be hard to fix

Despite the file url being present when testing the API in the browser, I noticed the JSON received by gallery-dl didn't include it. So checking the differences and a bit of testing, if you remove the Platform header from the request, it starts working again.

gallery-dl/gallery_dl/extractor/sankaku.py

Lines 195 to 200 in 1d3b9a9

	self.headers = {
	"Accept" : "application/vnd.sankaku.api+json;v=2",
	"Platform" : "web-app",
	"Api-Version": None,
	"Origin" : extractor.root,
	}

self.headers = {
"Accept" : "application/vnd.sankaku.api+json;v=2",
"Platform" : "web-app",
"Api-Version": None,
"Origin" : extractor.root,
}

How do I edit the file? All I got is a config file and a gallery-dl.exe. If there is a step-by-step guide to get this work again please let me know.

[taskhawk]

I edited the Python source files of my gallery-dl installation in Linux because they are run directly like that. In Windows the .exe file is a compiled form of the Python files and that's not easily modified, you would need to gather the source files, make the change(s) and recompile them into the .exe file.

But, the latest version was just released and it includes the fix, so just update to v1.29.0 and it should work for you again.
