[BUG]: the `DevToolsPlugin` with Edge as `preferredBrowser` does not seem to work

[Adam-it]

Description

So I configured the Dev Proxy to use DevToolsPlugin with Edge but when I start the devproxy I get the browser and dev tools but seems there is some error present in the devtools console and nothing is logged in the chrome debugger.

on the console, the devproxy logs the requests

but in the network tab of the devtools I don't get anything

Expected behaviour

I should see 'catched' requests in the Edge DevTools in Network tab

Actual behaviour

I don't get anything in the Edge DevTools in Network tab and I see some errors on console tab

Steps to reproduce

1. install dev proxy
2. configure DevToolsPlugin following the guide
3. start devproxy --no-mocks --log-level Info --failure-rate 0

Dev Proxy Version

0.13.0

Operating system (environment)

Apologies for the trouble @Adam-it

Can you share the version number of Edge you are using?

Is it possible for you to try the latest EdgeDev and see if you have the same issue?

Will check and come back with additional I go over the night.
Yes I will check the latest edgeDev as well 👍

[Adam-it]

@garrytrinder so the edge I am using is

however, I installed the latest EdgeDev and in this case, it works like a charm 🤩

[garrytrinder]

Thanks for the update @Adam-it

We will investigate and see if we can figure out what is going wrong on standard Edge.

@waldekmastykarz are you able to reproduce on macOS?

[waldekmastykarz]

Have you disabled the startup boost in Edge @Adam-it (https://learn.microsoft.com/en-us/microsoft-cloud/dev/dev-proxy/technical-reference/devtoolsplugin#known-issues)? Also, do you have all Edge windows closed before starting proxy?

Yes and no.
I will close all edge instances and recheck and let you know

[Adam-it]

@waldekmastykarz having all the Edge windows closed and then starting the proxy did not bring any difference and I still get the same errors

[waldekmastykarz]

Thank you for confirming. I'll try to repro asap and will let you know if I need any more info to fix it. Sorry for the trouble

no problem at all. It's working with the EdgeDev so it's not a blocker for me 🙂

[waldekmastykarz]

When you refer to Edge in your config, we're trying to run https://github.com/microsoft/dev-proxy/blob/df28158bb1aea4d96653db95c39f190478aa75a4/dev-proxy-plugins/Inspection/DevToolsPlugin.cs#L74. I wonder if Edge for Business is not a different version of Edge that we're not supporting at the moment? Could you double check if the installation directory matches what we've got?

[garrytrinder]

I'm experiencing a different problem when using Edge.

Screenshots are taken from the browser opened by Proxy. Note that no for Business is shown in the About screen.

Edge Dev works fine.

Install location for Edge is

C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe

If I open the About page after opening Edge myself, you see the same version but has for Business added to the name.

[waldekmastykarz]

@Adam-it it seems like you've opened dev tools for dev tools. If you look at your original window, it points to dev tools but the screen is empty meaning Edge failed to load dev tools. Try closing all Edge processes using Task Explorer and restarting proxy with dev tools pointing at Edge, and then expand dev tools from the side.
