DevTools is calling a VM service extension that no longer exists

[jacob314]

Repro: open DevTools.
flutter: Attempted to call extension 'ext.flutter.inspector.structuredErrors', but no service with that name exists

[kenzieschmoll]

Is it that the service extension doesn't exist or that we are calling it before it is registered?

[kenzieschmoll]

It looks like we do register this service extension here: https://github.com/flutter/flutter/blob/master/packages/flutter/lib/src/widgets/widget_inspector.dart#L1006-L1013

What kind of app are you connecting DevTools to?

I have switched the channel of flutter to beta (3.16.0-0.4.pre) and connected to windows, but still have this issue.

Same Here.

I'm creating a Devtools Extension, in simulated env it works well, but when I deploy, it stops working on real environment.
I can see the tab "Flutter Micro App", but it's not possible to enable it

I still see this in the Chrome DevTools console of DevTools.

Steps to repro:

• Run an app
• Copy-paste DevTools URL into browser window
• Open up Chrome DevTools for the DevTools instance

Bump, having this issue with a normal dart app, not flutter.
Repro:

• Run the app
• Get the link and paste into browser
• Press enter and check JS console
