angularjs directive isolated-scope JavaScript

I'm wondering if anyone has experience with I just started working with I'm working on a personal project and I'm working with AngularJS 1.8 and have created a custom directive that utilizes an isolated scope. However, I'm working with an scenario when trying to pass parameters to the directive, as the values are not being recognized correctly. Hereโ€™s how Iโ€™ve set up my directive: ```javascript app.directive('myCustomDirective', function() { return { restrict: 'E', scope: { param1: '=', param2: '@' }, template: '<div>{{ param1 }} - {{ param2 }}</div>', link: function(scope, element, attrs) { console.log('Parameter 1:', scope.param1); console.log('Parameter 2:', scope.param2); } }; }); ``` In my HTML, Iโ€™m using the directive like this: ```html <my-custom-directive param1="someModel" param2="staticValue"></my-custom-directive> ``` The question I'm working with is that `param1` seems to be `undefined` when the directive initializes, although `someModel` is defined in my controller. The console logs in the link function are showing `Parameter 1: undefined` and `Parameter 2: staticValue`. I've checked that `someModel` is indeed defined in the controller and that the directive is being used correctly. I tried enclosing `someModel` in double curly braces like this: ```html <my-custom-directive param1="{{ someModel }}" param2="staticValue"></my-custom-directive> ``` But that led to an behavior: `[$parse:syntax] Syntax behavior: Token '}' is unexpected, at column 12 of the expression [someModel}]`. Iโ€™ve also verified that `someModel` is not being altered during the digest cycle. Is there something Iโ€™m missing regarding the passing of parameters to the isolated scope? How can I ensure that `param1` is correctly recognized as the value of `someModel`? This is part of a larger CLI tool I'm building. I'm using Javascript latest in this project. I'm open to any suggestions. I recently upgraded to Javascript latest. Thanks for any help you can provide! This is happening in both development and production on Ubuntu 20.04. How would you solve this?
