Try this in your background script. Many of the old methods have been deprecated now, so I have refactored the code. For my use I'm only installing single content_script file. If need you can iterate over chrome.runtime.getManifest().content_scripts array to get all .js files.

chrome.runtime.onInstalled.addListener(installScript);

function installScript(details){
    // console.log('Installing content script in all tabs.');
    let params = {
        currentWindow: true
    };
    chrome.tabs.query(params, function gotTabs(tabs){
        let contentjsFile = chrome.runtime.getManifest().content_scripts[0].js[0];
        for (let index = 0; index < tabs.length; index++) {
            chrome.tabs.executeScript(tabs[index].id, {
                file: contentjsFile
            },
            result => {
                const lastErr = chrome.runtime.lastError;
                if (lastErr) {
                    console.error('tab: ' + tabs[index].id + ' lastError: ' + JSON.stringify(lastErr));
                }
            })
        }
    });    
}
