To fix this, the code below should show a respective error message instead of the current one (text) if the 413 response status code is detected. A new internationalization string would need to be added.

misskey/packages/client/src/scripts/upload.ts

Lines 86 to 90 in d3e242a

	alert({
	type: 'error',
	title: 'Failed to upload',
	text: `${JSON.stringify(ev.target?.response)}, ${JSON.stringify(xhr.response)}`
	});

Would be nice to also fix the title to also be internationalized instead of hard coded as English in the process.

In the current develop branch, if the server returns 413 with a non-JSON response, no error is displayed on the frontend because the JSON parsing fails and an uncaught exception is raised.

misskey/packages/frontend/src/scripts/upload.ts

Lines 82 to 88 in 8dc60cd

	if (xhr.status !== 200 || ev.target == null || ev.target.response == null) {
	// TODO: 消すのではなくて(ネットワーク的なエラーなら)再送できるようにしたい
	uploads.value = uploads.value.filter(x => x.id !== id);
	if (ev.target?.response) {
	const res = JSON.parse(ev.target.response);
	if (res.error?.id === 'bec5bd69-fba3-43c9-b4fb-2894b66ad5d2') {

As @Johann150 mentioned, we can solve this by displaying a user-friendly error message when status code 413 is detected.
May I start working on this issue?
