unable to attach vscode path variables (${file}), etc.. to devtools,

[SirBecalo]

Environment (please complete the following information):

• OS (e.g., Windows 10): ubuntu 20.04
• Extension version (e.g., 1.2.3): 1.4.6

Describe the bug:

unable to get my index.html to launch by default when "launch instance" is pressed, head/headless. problem encountered using relative vscode path variables: "${workspaceFolder}", "${file}". i tried in both default entrypoint and default URL fields, keeping the other at default value. i also tried setting both. i tried setting url to workspace and entrypoint to "index.html" Repro steps:

fresh install of extension, open index.html in your project folder, head to extension in activity bar, click "more settings" enter any vscode file variable with/without quotation marks such as "${workspaceFolder}" into url, inter index.html into entry point click the "+" button with hover status of "open new tab", find blank screen with this url:http://%24%7Bworkspacefolder%7D/ Expected behavior: open index.html

i wanted to load the contents of index.url by using the file url. the file url seems corrupt Additional context:

interesting behavior, when i try to change the url in a launched devtools instance to http://localhost:8080/${relativeFile} t he browser automatically parses it to: http://localhost:8080/$%7BrelativeFile%7D. making me think vscode is not doing any kind of proccessing on the variable, and passing the "http://localhost:8080/${relativeFile}" in URL field of launch.json just gets passed "as is" to edge.

show the launch config that you use

sorry for the wait, i forgot to submit (and later thought i did.) here is my current launch (but ive tried multiple)

{
    "configurations": [
        {
            "type": "pwa-msedge",
            "name": "Launch Microsoft Edge",
            "request": "launch",
            "runtimeArgs": [
                "--remote-debugging-port=9222"
            ],
            "url": "${file}", // Provide your project's url to finish configuring
            "presentation": {
                "hidden": true
            }
        },
        {
            "type": "pwa-msedge",
            "name": "Launch Microsoft Edge in headless mode",
            "request": "launch",
            "runtimeArgs": [
                "--headless",
                "--remote-debugging-port=9222"
            ],
            "url": "${file}", // Provide your project's url to finish configuring
            "presentation": {
                "hidden": true
            }
        },
        {
            "type": "vscode-edge-devtools.debug",
            "name": "Open Edge DevTools",
            "request": "attach",
            "url": "${file}", // Provide your project's url to finish configuring
            "presentation": {
                "hidden": true
            }
        }
    ]
}

note: in this instance, that was a fresh launch.json with only the url changed. ${file} should resolve to:

/home/sirbecalo/Desktop/dev/TOP/css-exercises/flex/05-flex-modal/index.html

previous launch gives this error:

also tired to rewrite launch.json to only this:

{
    "configurations": [
        {
            "type": "vscode-edge-devtools.debug",
            "request": "launch",
            "name": "Launch Microsoft Edge and open the Edge DevTools",
            "url": "http://localhost:8080/${relativeFile}",
            "webRoot": "${workspaceFolder}"
        }

    ]
}

actually opening edge, but giving me this URL:
