Copper App not installed

engrjislam commented 5 years ago

I got appId "incnkikhjmmhligicpbaalagdmaeebaa" on chrome://extensions/ and is replaced the previous appId at extension/endpoint/ClientPortChrome.js according to step 4. Then I tried to access an example url at the very first popup and found a error as below.

URI:

coap://californium.eclipse.org/

Error:

This extension needs the Copper application to send Coap-Messages. Please install the app (Chrome Web Store) and reload.

Web store link:

web store link is https://chrome.google.com/webstore/detail/incnkikhjmmhligicpbaalagdmaeebaa

Any help or instructions?

NB: I think, no extention is available for "incnkikhjmmhligicpbaalagdmaeebaa". Firefox has removed copper extension for some security issues from their official extension list (I found this in a blog post).

@engrjislam so, coap debug, Do you have a better solution?

engrjislam commented 5 years ago

No, so far I couldn't find any other solution for this @Allen-xcl.

Hi, is there any solution for this since I'm having the same problem? I changed the AppID in the JavaScript file but it gives me the same error.

engrjislam commented 5 years ago

There are several possible reasons behind this which is mentioned at firefox

The developer removed it. Developers commonly do this because they no longer support the extension or theme, or have replaced it.
Mozilla removed it. This can happen when issues are found during the review of the extension or theme, or the extension or theme has been abusing the terms and conditions for addons.mozilla.org. The developer has the opportunity to resolve the issues and make the add-on available again.

Ok, thank you. So there's no way to use the Copper plugin both in Chrome and FireFox?

Oh, I try to install the extaension(Copper) and get the same problem. But I finally find the way to solve it.

At first, we should open chrome://extensions/ to import Cooper4Cr/app(directory).
Than, we can find a new item at the bottom of chrome://extensions/ and Its name is "Copper (Cu4Cr) Application - 0.1.0". you should copy its ID.
The most important step is that you must use the ID to replace the appID by modify the JSfile (Copper4Cr\extension\endpoint\ClientPortChrome.js) let appId = "jojoaognefnjmbpadeknmmjebfaacegb"; please use your ID. Otherwise, you maybe cannot solve the problem and many people maybe need to do the step.
At last, you need to click Load the unzipped extension

you can use the extension without the error when you carefully read and do. In addition, I am sorry my bad English..... Hope my reply can help you.

I have the same issue. Changed the App ID and it says that ID is not an APP and will not continue. Sounds like Chrome changed something. Or the Author doesnt want to support this anymore.

engrjislam commented 5 years ago

It works fot me! Look at the instructions and follow https://github.com/mkovatsc/Copper4Cr/issues/3#issuecomment-497754418

cdfpaz commented 5 years ago

works for me too, in order to work you have to add both 'extension' and 'app' folder, and update file 'endpoint/ClientPortChrome.js' on extension folder with the id generated for the app

I struggled a lot with this issue and I figured out that:

In chrome://extensions/ page, the copper plugin appears twice, in Apps section and in Extension seciton
Use the ID in the apps section (scroll down to get it) and not the extension this made it work for me on the latest chrome

As mentioned by @bzero, add both the "app" and "extension" folder one by one when you click on "Load unpacked". Then copy the "ID" under "Chrome Apps" and update under "extension/endpoint/ClientPortChrome.js". Still works in Oct, 2020 :)

i have some issue, and i already follow this instruction, but its not work for me:(

LuchkaOnTheMoon commented 1 year ago

@MartaDiana as far as I understand, Google has dropped supporting Chrome Apps starting from July 2022, then completely inhibited the possibility to run Chrome Apps from March 2023, according to this note.

The simplest solution (even if maybe not very elegant) is then to download and use a previous version of Chrome here. I succeeded with Chrome version 107.0.5304.122
