Widget upload bug: jQuery.Deferred exception: e is not a function

[heymartinadams]

Description

Upon uploading an image from the desktop, I get the following issue:
jQuery.Deferred exception: e is not a function

Steps to reproduce

1. Sign up at simplerlist.com
2. Fill out your name, then try to upload a profile photo.
3. After upload, I get a blank screen:

4. The console says this:

Environment

• widget version: "@uploadcare/react-widget": "^2.2.0",
• node -v: v16.16.0

For what it’s worth, I’m using next-safe to limit API calls to third-party libraries. Not sure if that breaks Uploadcare.

Hey @heymartinadams,

next-safe is definitely not a problem.

Looks like there are some naming collisions on js minification stage.

Are you using the default next.js webpack config or the custom one?

[heymartinadams]

@nd0ut I’m using the following NextJS config:

const nextConfig = {
	compiler: {
		removeConsole: process.env.ENV !== 'dev'
	},
	// env variables that don’t begin with `NEXT_PUBLIC_` need to be assigned here
	env,
	experimental: {
		newNextLinkBehavior: true,
		images: {
			allowFutureImage: true,
			unoptimized: process.env.ENV === 'prd_capacitor'
		}
	},
	headers,
	images: {
		domains: ['images.unsplash.com']
	},
	pwa: {
		dest: 'public',
		// TODO: process.env.ENV === 'dev' || process.env.ENV === 'prd_capacitor'
		disable: true,
		register: true,
		skipWaiting: true,
		runtimeCaching
	},
	reactStrictMode: false,
	redirects,
	swcMinify: true,
	webpack: config => config
}

Is it Next.js v12.3.0?

Anyway, please try to disable swcMinify so Next.js will use terser in that case. I'm pretty sure that SWC minifier causes this problem.

I will prepare an issue to next.js If it helps.

Thanks so much, @nd0ut! That was the issue indeed ☺️

Hi @nd0ut can you please share a link to an issue to NextJS please, I've met the same problem, so I would like to subscribe to updates.

[heymartinadams]

NextJS 13 now has swcMinify enabled by default. https://nextjs.org/docs/advanced-features/compiler

Any update on when we can use it, @nd0ut?

@KrokoYR @heymartinadams

Sorry guys, I haven't created an issue to next.js repo yet.
Writing a minimal reproducible example becomes harder than I thought.

Here it is - swc-project/swc#6463

This problem was fixed in next@13.0.5
