Can't load source maps cluttering console

I’m a web developer and rely on my console, and this morning I started getting all of these warnings clogging up my console. Makes my work more difficult/annoying.

Having trouble with Bitwarden Browser Extensions? (Chome, Firefox, etc)

Until this is fixed, I did just find a setting in Chrome Dev tools Console tab called “Selected context only”. Turning that on hides the errors for now.

Hi @Nicodemus - have you tried updating your browser extension? There was a recent release that fixed some of the wierd behaviour on Chrome, and another one coming down anytime now.

#4

Thanks for the help.

I have version 1.56.1 installed, which is the latest version on the chrome store.

OK, great. I see on the BW Github page that they have added bugfixes and are currently on release 1.56.3. Hopefully it appears on the Chrome store soon. :crossed_fingers:

Same error here.
I removed the extension and installed it again from Chrome Webstore and still have the problem.
I am using the latest Brave browser.

Same issue as @Nicodemus here wink

I’m using Chromium 98.0.4758.80 with Bitwarden extension 1.56.4.
The issue does not occur using Firefox 97.0 (64-bit) with Bitwarden extension 1.55.0.

Are any developers in this thread?

We’re tracking the issue here: https://github.com/bitwarden/browser/issues/2365 - it should be resolved shortly :+1:

This error is appeared because the WebView can’t recognize the URL Scheme,for example, the WebView will usually recognize only http and https, anything other than these. So WebView cannot parse it to right place, we should use intent to redirect the url. for example – intent://,market://,app://,mail:// etc will not be recognized by webview unless we add a handler to handle these url scheme or by disabling these schemes and only load http and https schemes.

This error has no any specific solution till now. Android user and PC user all are facing this error which needs to be sought out. There’s a long-standing bug in Chromium regarding how links without protocols are handled. It occasionally is patched, but seems to keep resurfacing. In some cases, prefixing your links with http:// (or https://) should resolve the issue for you.

Also, in some cases, try to add target=“_blank” in your URL Scheme/Code. for example:

<a href="mailto:[email protected]" target="_blank">Link Text</a>
