webpack-dev-server: Uncaught TypeError: Cannot read property 'replace' of null

Hi, with version 1.14.1 I’m receiving this error:

Uncaught TypeError: Cannot read property 'replace' of null

I’m using an inline script in the index.html to load the .JS file (which is in the folder declared by publicPath) and I enabled the hot module replacement to receive updates.

Using version 1.14.0, it works fine (so at the moment I am not updating the webpack-dev-server module to 1.14.1).

Same problem here because of the Google Tag Manager script in the index.html

Just to point out for anyone else having the same issue - For me this issue occurred because of using the Poper Blocker chrome extension. I didn’t have no script tag without ‘src’ attribute in the page I was working on, so it was very confusing to understand that this extension injects a script tag (without an ‘src’ attribute) during the page loading.

I have disabled the extension until this issue will be fixed.

Also getting this problem with the similar script injections. The solution provided above (downgrading to 1.14.0) works for me.

I was able to work around this with a hack-ish change:

<script>
    document.currentScript.src =''; // So that the script executes, but later has a src.

    // ... Do rest of work.   
</script>

FYI: This is happening when you have a <script /> tag in your code that doesn’t have a src attribute.
