I'm trying to get the content of some background requests made while loading a website. I decided to use the devtools API, so I'm doing something like:

function handleRequestFinished(request) 
 request.getContent().then(content => 
 // do something with content here
 );
 
}
browser.devtools.network.onRequestFinished.addListener(handleRequestFinished);

Not exactly my code, but just a skeleton of how this is supposed to be done if we follow the docs1.

So what happens is, for some urls I get as content a list like [null, null]. I suspect this is a bug or a permissions thing (maybe there are special permissions needed to get the content of a request if it is 3rd party/https/-add whatever arcane condition Mozilla considered here-).

I'm considering switching to webRequest, but in any case, if someone has a clue about what is happening here I would very much appreciate your help.

Update: Seems the problem is more related to big binary files. This API returns the base64 representation of binary files, and it seems that at some size it just stops returning anything. I've tried setting devtools.netmonitor.responseBodyLimit with no luck.

PS: On the network tab, the content of those responses appears just fine.. The content on the network tab is truncated. Same as the content obtained through webRequest API. The only way to get the full response is by doing a curl...
