Errors in the console log

[my-password-is-password]

When I installed uMatrix in a dev build of Chromium theres was an error for "collect errors".

So I checked stable chrome and the errors were also there if you inspect background.html.

• Error in event handler for webRequest.onBeforeSendHeaders/2: undefined is not a function (traffic.js:475:62)
• Uncaught TypeError: Cannot read property 'repoObsolete' of undefined (updater.js:48)

Using µMatrix 0.8.0.0-alpha.4

I just unzipped the package and installed and there is no error. It is as if there is a source with a javascript syntax error. Can you scroll up the console and show me the first lines instead?

The first line is

Error in event handler for webRequest.onBeforeSendHeaders/2: undefined is not a function
Stack trace: TypeError: undefined is not a function
    at µMatrix.webRequest.onBeforeSendHeadersHandler (chrome-extension://egcodlnmejbejgffgmjihcknjmlmnobb/js/traffic.js:475:62)

Launching Chrome and going straight to the console log.

Ok, I removed code to hold back the request handler, I need to hold it back until all is installed. I will just do it differently his time, it was kind of clunky before. I suppose you had something net requesting while you enabled uMatrix.

It was a request to https://www.google.com/searchdomaincheck?format=url&type=chrome.

Should it be µm.scopeFromUrl(....) instead of this? When I changed it the error went away.

Thanks for spotting this, good code review. I don't actually need to call this function anymore as in HTTPSB, the page hostname is always used now.

I had referer-removal disabled, hence I couldn't repro the bug.

Saw 2 more errors in the console. I have every checkbox in Privacy and Hosts Files checked.

Using µMatrix 0.8.0.0-alpha.6.

First one can happen in normal circumstance when behind-the-scene matrix blocks the requests used by uMatrix to fetch remote resource, or if there is no network connection.

Second one is yet another thing I missed to revise when I imported code from uBlock.

Ah yes, I miss the entry in messages.json for the first one.
