DevTools 解析 SourceMap 失败：chrome-extension

Question

A week ago i think, I started getting warning messages in my google chrome console.

Clearing cache doesn't change anything, the messages disappear only in incognito mode.

Any ideas how to get rid of these warnings ?

Answer 1

I had this problem with the LastPass browser extension. I proved my theory by disabling LastPass and reloading the site in question - the warnings were gone!

I really didn't want to disable the JavaScript and CSS source maps so I have made the following change below:

Pending an update from the LastPass that addresses the issue, I have temporarily fixed this by changing one of the settings in the Extension settings for LastPass.

I had this setting previously set to On all sites , which was injecting the LastPass code on all sites blindly. With this change you need to right click on the Username/Password box to enable last pass, but on the plus side there are no warnings in the console anymore.

I consider this a temporary workaround until either Google or LastPass fix the issue.

EDIT: There is also a checkbox in the settings dialogue for the Console tab itself called Selected context only . Ticking this will remove the warnings and errors from Chrome extensions. Note this setting is not persisted - you'll have to click it each time you open the Dev Tools.

Answer 2

I've just used Chrome Console Filter -chrome-extension . I see everything except chrome-extension output.

Answer 3

对我来说，它是 McAffee Web Advisor Chrome 扩展程序 - 已删除并且消息消失了 :)

Answer 4

this worked for me:

1. Find the path to the extensions. Type this in chrome: chrome://version/ . Look for the profile path. this location is where the extensions are saved.

2. Open the location with the file explorer. In my case it was something like (AppData\\Local\\Google\\Chrome\\User Data\\Default\\Extensions\\hdokiejnpimakedhajhdlcegeplioahd\\4.51.0.1_0) The error was with the last pass plugin.

3. Create the missing maps. In my case it was: sourcemaps/

Note that i only created the empty maps.

Answer 5

All I did is disable my LastPass extension(plugin), clear browsing data, hard reload the page and it works fine. It might be another plugin for you

Answer 6

You need to open settings from the debug console

Then you disable one of chrome's option (They added it recently)

Just refresh the browser and all ready
