chrome-extension send message to tab which has NOT been injected and ignore error "caught (in promise) Error: "

The scenario is I have is

  1. On 'options page' user can add / delete urls to block. When user clicks save button, the updated list of urls is saved on storage
  2. On 'popup page' user clicks start button and all the urls in storage are blocked (by overriding innerHtml). On stop all the injected tabs are sent stop message (restore the original html)

Additionally on 'options page' when user clicks on delete a url and save, it will send stop message to all the tabs irrespective they are injected or not. the reason for this is that I do not know which url existed before and which have been removed

when i send message to all the tabs using code

try {
        let tabs = await chrome.tabs.query({}) // all the tabs
        tabs.forEach((tab) => {
                const resp = chrome.tabs.sendMessage(tab.id, {type : 'StopTimer'})
        })
    } catch (err) {
        console.log('No matching tab', err)
    }

I get the following error for tabs which are not injected

caught (in promise) Error: Could not establish connection. Receiving end does not exist.

I want to simply catch (ignore) error. to prevent showing it as error on extensions page. Right now this catch block is not catching the error.

Is there a way to do it? Else I have to figure out in 'background.js' all the tabs which have been injected and then send the message to those

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
