Invalid Isolate Scope Definition

Invalid {3} for directive '{0}'. Definition: {... {1}: '{2}' ...}

When declaring isolate scope the scope definition object must be in specific format which starts with mode character (@&=) with an optional local name.

myModule.directive('directiveName', function factory() {
  return {
    ...
    scope: {
      'attrName': '@', // OK
      'attrName2': '=localName', // OK
      'attrName3': 'name',    // ERROR: missing mode @&=
      'attrName4': ' = name', // ERROR: extra spaces
      'attrName5': 'name=',   // ERROR: must be prefixed with @&=
    }
    ...
  }
});

Please refer to the scope option of the directive definition documentation to learn more about the API.
