Angular $http.post gives Error: Invalid argument. in IE 8

Question

App works fine in Chrome, Safari, Firefox etc. But in IE the following code gives an error: ``` $http.post('/myurl', 55) .success(...) .error(...) ``` The error: ``` Error: Invalid argument. ``` Happens after `$rootScope.$digest();` in the `$apply` function in `angular.js` Any ideas that could help debugging this mysterious Microsoft Internet Explorer™ error message?

Accepted Answer

so... I turns out adding quotes makes IE happy.

This works in Firefox, Chrome, Safari, etc. :

```
$http.post('/myurl', myNumberVariable)
```

But fails in IE (8). However, this works in IE 8:

```
$http.post('/myurl', myNumberVariable.toString())
```

Didn't get clarification if this was due to angular or the java backend method that was tried to call.
