Platformio-vscode-ide: In VS Code: Unable to open 'PIO Home': Cannot read property 'theme' of undefined.

Created on 3 Mar 2018 · 24Comments · Source: platformio/platformio-vscode-ide

After a fresh install of VS Code and Plaformio-IDE on W10,
when clicking on the PlatformIO Home button I get:

"Unable to open 'PIO Home': Cannot read property 'theme' of undefined."

I tried to uninstall, reboot and reinstall several times, still the same...

Temporary workaround:

in .vscode\extensions\platformio.platformio-ide-0.13.0\lib\home.js
replace lines,

 return 
      <html>
      <body style="margin: 0; padding: 0; height: 100%; overflow: hidden; background-color: ${theme === 'light' ? '#FFF' : '#1E1E1E'}">
        <iframe src="${pioNodeHelpers.home.getFrontendUri(params.host, params.port, { start, theme })}"
          width="100%"
          height="100%"
          frameborder="0"
          style="border: 0; left: 0; right: 0; bottom: 0; top: 0; position:absolute;" />
      </body>
      </html>
    ;

with lines from previous version of this file

return `
  <html>
  <body style="margin: 0; padding: 0; height: 100%; overflow: hidden; background-color: #fff">
    <iframe src="http://${ params.host }:${ params.port}?start=/${ uri.authority }" width="100%" height="100%" frameborder="0" style="border: 0; left: 0; right: 0; bottom: 0; top: 0; position:absolute;" />
  </body>
  </html>
`;

Then restart vscode.

In my case, after returning back the changes also continue to work. Apparently something produced registration and the system works even after reinstallation. Tested on Win 8.1 and Win 10

Same problem.
Unable to open 'PIO Home': Cannot read property 'theme' of undefined
Solution works

VladimirAkopyan on 4 Mar 2018

same problem here,

workaround works:

I copied the file home.js (you find it in the user directory)
Modified the lines mentioned above
started Visual Studio Code
PIO Home launches
closed Visual Studio Code
copied back the home.js file (revert any changes)
Visual Studio Code is running anyway

Please fix asap, getting started at clean installation with crazy error will made almost all people switch to another IDE...

Im having the same problem and want to try this fix but I'm unable to find the home.js file to change it. How did you open it?

Sory for the issue. We've just fixed it quickly and released 0.13.1. Please update the extension.

@dylanlrrb does it work for you now?

ivankravets on 5 Mar 2018

I have followed above instruction except that my platformIO folder is 0.13.2.
But unfortunately, the home page still cannot be opened. There has no error but keep showing the blank screen for loading.
I'm working behind proxy, and login is required. I have entered the proxy login when vs.code started, is there any other changes required? But it works fine before the upgrade.

P.S. after waiting for few minute, the PIO home page closed automatically, and the following error was show in the Welcome page:

Unable to open 'PIO Home': An unknown error occurred. Please consult the log for more details..

@Super169 could you try to open PIO IDE Terminal and type pio home --port 8888. Do you see any errors?
