I'm retrieving some images from one of my chrome extension folders to the website DOM and everytime I reload the extension I'm getting a 'Extension Context Invalidated' error. Same thing happens when I do a 'chrome.storage.local.set'.
Doing some research I have realized that this error has to do with the facts well explained on this answer but since I'm not messaging between my content script and the background.js I wonder why this happens.
This is the part of my script (injected via chrome.tabs.executeScript in the popup.js) where I'm getting the error, I'm basically injecting images from one of my extension folders to the website DOM:

Reset to default 6Upon reloading extension, Your old content scripts will continue to reside in opened pages until you refresh them. However their context with respect to Chrome extension would be lost.
Just one liner to avoid the situation:
if(chrome.runtime.id == undefined) return;
I want to explain what I did in order to keep this:
Basically I wrap everything that was creating this error with :
typeof chrome.app.isInstalled !== "undefined"”
I still trying to figure out why this is working, to be honest. I understand that every time I update the extension the content scripts are still injected on the website (in my case, grabbing dom elements, storing data to chrome local storage, etc) but I don't get why that statement avoid this to happen since the extension is still installed on my Browser, I'm just updating the files.
If someone can give a more in-depth explanation of why this is working for me please shine a light here.
