"Missing Command Error" when running in browser

[EvHaus]

After installing the plugin and calling init(), when I run the app in my browser I get this back from the "error" event:

Error: Missing Command Error
    at fail (http://localhost:8000/plugins/phonegap-plugin-push/www/push.js:55:45)
    at module.exports (http://localhost:8000/cordova.js:925:17)
    at http://localhost:8000/plugins/phonegap-plugin-push/www/push.js:61:9

This error is not descriptive enough. I don't know what's going wrong.

Wrap the code in some condition so it's not executed in the browser. There simply is no backend for the javascript code in the browser because the plugin is only available on iOS, Android and Windows for obvious reasons.

[EvHaus]

Then why does the plugin mention support for the "browser" platform? That's a bit confusing.

[h4rm]

That documentation states:

Supported Platforms

Android
iOS
Windows Universal

Hmm. Sorry about that. I got confused when I saw that the plugin installed itself into the "browser" platform directory.

$ cordova plugin add phonegap-plugin-push
Fetching plugin "phonegap-plugin-push" via npm
Installing "phonegap-plugin-push" for android
Installing "phonegap-plugin-push" for browser

Not sure why cordova says they support the browser platform and whether it's different in phonegap.

I had the exact same 'Missing Command Error' error reported in the Chrome dev console (that's how I found this thread) and looking at the Cordova file plugin repository, they claim they do support the browser platform:

both here

https://www.npmjs.com/package/cordova-plugin-file

and here

https://github.com/apache/cordova-plugin-file

So does this mean the question still remains open?

@dorontal no, we added browser support awhile back.

Got it, thanks. So my problem still stands. Here's my code snippet that causes it:

        window.addEventListener(
            'filePluginIsReady',
            () => {
                console.log('File plugin is ready');
                File.getFreeDiskSpace().then(
                    (arg: any) => {
                        console.log('getFreeSpace() => ' + arg);
                    },
                    (err: any) => {
                        console.log('Error calling getFreeSpace(): ' + err);
                    }
                );
            },
            false);

and here's the most recent Chrome browser's dev-console output:

File plugin is ready
Error: exec proxy not found for :: File :: getFreeDiskSpace
Error calling getFreeSpace(): Missing Command Error

[ NOTE: File is just cordova.file and the code is in Typescript. ]

Has anyone seen similar problems reported:

• exec proxy not found
• Missing Command Error

when trying to use the cordova / phonegap file plugin in chrome?

I read both the 'chrome quirks' and 'browser quirks' sections of the README but did not see anything applicable - perhaps I missed something.

Thanks!

EDIT: my apologies, just realized I posted here in the wrong place. It may not be related to the original question. Will figure out where to post appropriately.

error "Missing Command Error"

I too need an answer to this and I can't find it anywhere. What is the final answer? If browser support was in fact added, as macdonst stated, then what's the cause of the error? If browser support doesn't exist then the Couchbase PhoneGap Getting Started guide needs to not represent that it does exist. The guide clearly shows the app running in a Chrome browser with Developer Tools open, as well as explicitly represents that it does run in a browser.

Are we supposed to see this message? I got this message when I tried adding cordova-plugins-admob-free into cordova plugins.

Does this mean that are certain plugins that only work with iOS/android/windows phone and won't be able to show up on browser?
