How to intercept response for file upload via filechooser/

Website uploads file immediately on file change. I want to intercept JSON response of this upload. Is it possible?

page.on("filechooser", (fileChooser: FileChooser) => {
	fileChooser.setFiles(["/Volumes/Data/Dropbox/Public/111.jpg"]);
});
await page.click('input[name="up[]"]');

Ok, solved with

this._page.on("response", async (response) => {
	if ("url what i needed" === response.url()) {
		console.log(await response.json());
	}
});

One question related to this subject, so I will ask in closed thread.

From here

const response = await page.request.fetch(route.request());

How it should be modified for multipart data? Or probably I can get json of complete response already?

Because const response = await page.request.post(route.request()); causing error on website (it’s 3rd party website so I can’t say what a reason here)
