Issue opening DevTools when using allow and block list in Edge

[neckermann]

We have our Edge browser locked down to just a few sites. With the sites in the allow list and a block list of *.

When this is in place, we are unable to open the Edge Dev tools.

Can you share the url handler we need to add to the allow list for this to work.
If we move our block list to just http://* or https://* dev tools open so I assume it is something like
devtools://*

Thanks for reaching out about this. Let me try to find this information for you and get back to you as soon as I can.

@captainbrosset any luck finding the url handler?

[captainbrosset]

Not yet unfortunately, but I'll make sure to update this thread as soon as I do.

@neckermann you can probably start with adding devtools://devtools/* to the allow-list. You might also need to add https://devtools.azureedge.net/* to the allow-list.

I'm not sure if this will work, but it's worth trying out. Let me know!

Something else worth trying is changing the DeveloperToolsAvailability policy (docs). Your environment may be configured to not have DevTools available.

In fact, we ran into this with WebDriver here and documented the work around here: Use WebDriver to automate Microsoft Edge.

@captainbrosset
So it looks like devtools://* worked for us.

Thanks
