electron: mainWindow.webContents.openDevTools() throws error when loading new page

I am writing a simple Electron app. I am developing on Windows 10 with the Atom Editor. All my packages are up to date as this everything has been downloaded and installed in the past 2 weeks. I have mainWindow.webContents.openDevTools() enabled in my app.js file.
Once the main window loads… I have a menu item that I click which loads a new html page in the main browser window and in my command prompt window (not the browser console) I get the following error : [4104:0310/122311.704:ERROR:CONSOLE(6639)] "Uncaught (in promise) TypeError: Cannot read property 'scriptId' of null", source: chrome-devtools://devtools/bundled/inspector.js (6639) [4104:0310/122311.704:ERROR:CONSOLE(6639)] "Uncaught (in promise) TypeError: Cannot read property 'scriptId' of null", source: chrome-devtools://devtools/bundled/inspector.js (6639) My command prompt window is not running in legacy mode It should be noted that no other javascript is loaded or runs when the html page loads.

+1, happens after every reload but only if devtools is open. I don’t specify to open devtools from the main.js file.

Only when devtools is open Ubuntu 16.04.4 LTS electron 1.8.6 node v10.0.0 chrome 66.0.3359.139 (Official Build) (64-bit) Using electron-react-boilerplate in case it matters.

for me the error is printed out MANY times (see below).

I got the same error message as @biomade on windows 7, in Git bash, by checking Preserve log in devtools console tab. Unchecked Preserve log before reloading the view causes no error messages.

package.json

{
  "name": "test",
  "version": "1.0.0",
  "description": "",
  "main": "main.js",
  "scripts": {
    "start": "electron ."
  },
  "author": "",
  "license": "ISC"
}

main.js

const {app, BrowserWindow} = require('electron')
const url = require('url')
const path = require('path')
const {ipcMain} = require('electron')

let win

function createWindow() {
   win = new BrowserWindow({width: 800, height: 600})
   win.loadURL(url.format({
      pathname: path.join(__dirname, 'index.html'),
      protocol: 'file:',
      slashes: true
   }))
}

// Event handler for asynchronous incoming messages
ipcMain.on('asynchronous-message', (event, arg) => {
   console.log(arg)

   // Event emitter for sending asynchronous messages
   event.sender.send('asynchronous-reply', 'async pong')
})


// Event handler for synchronous incoming messages
ipcMain.on('synchronous-message', (event, arg) => {
   console.log(arg)

   // Synchronous event emmision
   event.returnValue = 'sync pong'
})

app.on('ready', createWindow)

index.html

<!DOCTYPE html>
<html>
  <head>
   <meta charset="UTF-8">
   <title>Hello World!</title>
  </head>
  <body>
   <script>
      const {ipcRenderer} = require('electron')

      // Synchronous message emmiter and handler
      console.log(ipcRenderer.sendSync('synchronous-message', 'sync ping'))

      // Async message handler
      ipcRenderer.on('asynchronous-reply', (event, arg) => {
         console.log(arg)
      })

      // Async message sender
      ipcRenderer.send('asynchronous-message', 'async ping')
   </script>
  </body>
</html>

Couldn’t be reproduced on debian-linux.

I get this when my app starts. Any ideas?

This is fixed in all currently supported versions of Electron.

Try replacing all the links in your application with the Link component from the ‘react-router-dom’ lib.

I was getting the same errors above until I replaced all the links with the Link component. I think it the error ‘TypeError: Cannot read property ‘_rawLocationToUILocation’ of null’ has something to do with the generated html.

//generic html
a to="/link" href="/link"

//generated by react-router-dom
a href="#/link"

I will look at it tomorrow.

I get the exact same error message. On the first build it does not complain, but It occurs when I have the electron application running and make a change to the application. Line 6639 of inspector.js gives very little info:

_parsedScriptSource(event){var script=(event.data);if(! script.sourceURL||script.isLiveEdit()||(script.isInlineScript()&&!script. hasSourceURL))

The application runs nevertheless and changes are reflected after rebuilding. When I close the devtools and reload the application I do not get an error. When I reload with the devtools open, it seems it gives an increasing amount of errors with every reload.
