error while getting tab from its id

[jack]

hi,

I get the tabid from onBeforeRequest listener like below:

chrome.webRequest.onBeforeRequest.addListener(function(details) {

        var current_tabId = details.tabId;

        chrome.tabs.get(current_tabId,function(tab) {

                         

         });

}, {urls: ['http://*/*', 'https://*/*']});

But I get the following error:

Unchecked runtime.lastError while running tabs.get: No tab with id: 70.

    at chrome.webRequest.onBeforeRequest.addListener.urls

How can it be possible that this tab does not exist? Are there some tabs which exist temporarily?

Thanks

Someone could guess the reason please?

May be due to pre-rendering / chrome instant. See the section "A note about tab IDs" at https://developer.chrome.com/extensions/webNavigation
