"DevTools failed to parse SourceMap" warning

[Nuc1eoN]

In Brave v1.3.115 if you open any page, go to the Inspector and open the console, there are the following warnings:

DevTools failed to parse SourceMap: chrome-extension://odbfpeeihdkbihmopkbjmoonfanlbfcl/sourcemaps/contentscript.js.map
DevTools failed to parse SourceMap: chrome-extension://odbfpeeihdkbihmopkbjmoonfanlbfcl/sourcemaps/inpage.js.map

At first I thought it's a website issue but it really seems to be tied to the brave browser.

Same issue here :(

I am experiencing the same issue. I thought it might be an extension problem but I've checked all my extensions and there are no issues. I am running Brave (stable) for Linux on Ubuntu.

Looks like this is caused by the Crypt Wallets extension (odbfpeeihdkbihmopkbjmoonfanlbfcl)

@Nuc1eoN @minaiism @EugenioAntonioBonanno can you folks confirm whether or not you've navigated to brave://wallet at any time?

[EugenioAntonioBonanno]

I have definitely navigated there.

I'm quite sure I haven't been at brave://wallet, and I definitely wasn't in the past 1 month. I ended up here because I'm also seeing the warnings in the console. I hope it helps.

[minaiism]

Same as @vdavid .I haven't been at brave://wallet whatsoever.

[bsclifton]

@ryanml even if you don't enable Crypto Wallets, the extension is always running. Visible in the Task Manager (Hamburger => More Tools => Task Manager)

[bbondy]

Hey @bsclifton that's not right for a fresh profile that hasn't navigated to brave://wallet on Release channel up to Nightly.
Nightly, Beta, and Dev also has some MetaMask compatibility work which will require you to select Crypto Wallets as your Dapp provider before it will display any warnings.

[bsclifton]

ah - ok my bad; I believe I did visit brave://wallet. I didn't realize it would run the extension even if Crypto Wallets is disabled / not used

[marcuswhybrow]

Disabling Crypto Wallets worked for me:

[zaxbux]

There's a source map comment in the affect files, but the source maps themselves are missing. The developers should disable source map creation in their asset build process.

Edit: Removing those comments fixed this issue.

Upstream issue

Looks like more errors are exposed (if source-map files are missing, error will now show where it didn't before)

And, currently source-maps from extensions aren't loaded even if they are provided.

I'm seeing this error for 1PasswordX extension, having disabled crypto wallets already.

@rebron - may I ask that someone remove the comments referencing a source map (or install the source map files)? the warning is rather annoying and distracts me when i'm trying to debug things in the browser... thanks!

[mrose17]

Thank you!
