[Documentation] Documentation website failed to load javascript resources

[marcosun]

• I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior

When visiting https://material-ui.com/demos/app-bar/, the website should load javascript resources, i.e. app-bar.js, _error.js, main.js, as specified in the html.

Current Behavior

Three javascript files cannot be accessed with response status code 404 (app-bar.js, _error.js, main.js). These resources' url address take the following pattern: https://material-ui.com/_next/826c5e81-cb19-43a7-b1d5-78a5a031a506/main.js.

However, when I visit documentation website from a new browser (previously Chrome, now Safari) on the same laptop, javascript resources can be successfully loaded although url address is not the same as before: https://material-ui.com/_next/0509e9cc-b04b-47a6-bbd3-17e3a66d2eac/main.js

Steps to Reproduce (for bugs)

Go to https://material-ui.com/demos/app-bar/ in Chrome and open up Developer Tools. Have a look at Network tab.

Context

Your Environment

It's serviceworker issue. Try clearing your cache.

Ok, after a little bit research I come up with this solution.

1. Click 'Clear site data' button which you can find here: DevTool -> Application -> Clear storage

If this blocks you indefinitely visiting documentation website as I have, then

2. Go to chrome://serviceworker-internals/ and unregister https://material-ui.com/

And now website is reacting again.

@oliviertassinari But how could this happen? Is there anything we can do to prevent this from happening again?

[oliviertassinari]

The issue could be coming from us, workbox or chrome. Let's see if more people are affected. For now, I'm closing the issue.
