Users reporting `Invalid manifest` error in CWS

[Artem Harutyunyan]

Hi,

We are getting numerous reports from our users trying to install our extension through the Web Store that they are getting an `Invalid manifest` error. There is a modal popping up that prevents them from being able to install the extension (see attached screenshot, and sorry for poor quality). This doesn't happen to everyone, and we weren't yet able to reproduce this ourselves. We are using Manifest v3. Any clues on what this could be?

Artem.

Does you extension has `commands` defined? I know an extension had this issue on Ubuntu and the owner of the extension fixed it by defining only a `default` key combination for the `suggested_key` config, instead of having a `windows` and `macosx` one. This is not related to manifest v3 btw, as the extension I am referring is still on mv2.

Hi Artem,

That is an interesting issue. Can you check if you saved the manifest.json file on your end as UTF-8?

And there are no special characters in it.

Thanks,

Hi,

I double checked the manifest.json, it doesn't have any special characters, and it's saved as a vanila text file:

-----

$ file -I manifest.json                
manifest.json: application/json; charset=us-ascii

-----

We also do have `commands` defined in the manifest, here is what it looks like:

-----

"commands": {
    "_execute_action": {
      "suggested_key": {
        "default": "Alt+B",
        "mac": "Alt+B"
      }
    }
  },

-----

We had it in there for a very long time though and Ubuntu users installed it without a problem in the past.

So it have to be a bug then, but I can guarantee you that I couldn't install that extension on Ubuntu Linux for months with the same error about the manifest being incorrect. Here is how the maintainer fixed it in the end https://github.com/md-reader/md-reader/commit/a50db14cd53d91b46cd8ebe59a4cd116c01630fe maybe you can find more information in their issue tracker. Now I can install the extension on my end.

Hi Artem,

Were you folks able to figure this out because a few of our users have started facing the same issue (while it does not happen with the majority of them)

[Artem from bardeen.ai]

We haven't, unfortunately. Normally suggesting users to upgrade to the latest version of Chrome works.
