'_item_' in '_item_ in _collection_' should be an identifier or '(_key_, _value_)' expression, but got '{0}'.
Occurs when there is an error in the identifier part of ngRepeat's expression.
To resolve, use either a valid identifier or a tuple (key, value) where both key and value are valid identifiers.
Examples of invalid syntax:
<div ng-repeat="33 in users"></div>
<div ng-repeat="someFn() in users"></div>
<div ng-repeat="some user in users"></div>
Examples of valid syntax:
<div ng-repeat="user in users"></div>
<div ng-repeat="(id, user) in userMap"></div>
Please consult the api documentation of ngRepeat to learn more about valid syntax.
