This works: Simple message passing with no nested call to chrome API in the onMessage listener.

content_script

chrome.runtime.sendMessage( message: "what is my windowId?" , function(response) 
// clearLocalStorage(response.allWindowsId);
 windowId = response.windowId;
 console.log(windowId);
);

background_script

chrome.runtime.onMessage.addListener(function(request, sender,sendResponse) 
 if (request.message === "buttonClick") 
 chrome.tabs.reload(sender.tab.id);
 sendResponse(message: 'handle button click');
 else if (request.message === "what is my windowId?") 
 sendResponse(
 windowId: sender.tab.windowId
 );
 
 return;
);

This doesnot work: Nested call chrome.windows.getAll in the onMessage listener.

background_script

chrome.runtime.onMessage.addListener(function(request, sender,sendResponse) 
 if (request.message === "buttonClick") 
 chrome.tabs.reload(sender.tab.id);
 sendResponse(message: 'handle button click');
 else if (request.message === "what is my windowId?") 
 // additional code here
 chrome.windows.getAll(function(windows) 
 sendResponse(
 windowId: sender.tab.windowId,
 windows: windows
 );
 );
 
 return;
);

I've also tried to make the call chrome.windows.getAll async using chromeExtensionAsync, but no luck yet.

The following is the error message. It seems that the call to window.getAll happens after the function onMessage returns, even though I've marked this function async by the final return; statement.

Error handling response: TypeError: Cannot read property 'windowId' of undefined

Unchecked runtime.lastError: The message port closed before a response was received.

  There's an official trick: move return into the else branch before } and make it return true. See Chrome Extension Message passing: response not sent

  Solved! It could be solved without move return elsewhere. Making it return true; is enough to solve it.

I just published an OSS library that helps with this case: @wranggle/rpc

Take a look at the BrowserExtensionTransport. It includes an example for making remote calls between a content script and the background window.
