Unable to properly call a UI Script from a Catalog Client Script.

[RyoyaFukuda]

Hi,all.

I am trying to call a UI Script from a Catalog Client Script.
This development is being done within a custom application.

Here is the script. And error message is ''UI Script  x_16799_test.TestUIScript is loaded but can not find dummyFunction or result is fraud. Result: null'
Could you please tell me why the UI Script cannot be called successfully?

Catalog Client Script
Type : onChange

UI Type : All

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }

    var value = newValue;
    var name = 'u_int_test';
    var uiScriptName = 'x_16799_test.TestUIScript';


    if (typeof g_ui_scripts !== 'undefined') {
        // Workspace（WEP）
         g_ui_scripts.getUIScript(uiScriptName).then(function(result) {
        if (result && typeof result.dummyFunction === 'function') {
		//  if (result && typeof result.formatAndTruncateNumber === 'function') {
            g_form.addInfoMessage('UI Script ' + uiScriptName + ' is loaded and find dummyFunction');
            result.dummyFunction();
        } else {
            g_form.addInfoMessage('UI Script ' + uiScriptName + ' is loaded but can not find dummyFunction or  result is fraud.  Result: ' + JSON.stringify(result));
        }
    }).catch(function(error) {
        g_form.addErrorMessage('UI script failed to load: ' + error);
    });
    }
}

UI Script
API:x_16799_test.TestUIScript

(function() {
    return {
        dummyFunction: function() {
            // do noting
        }
    };
})();

Could you please confirm the scope of your catalog client script. From your error message, it seems to be coming for scope issue.

@Tanushree Maiti 

I am developing a custom application named "Test."
Catalog Client Script and UI Script applications are both "Test".
Do you need any other information?

Can you validate your UI script code. I guess type is missing there.

• Application: x_16799_test
• Name: TestUIScript
• API Name: x_16799_test.TestUIScript

(function() {
        return {
        dummyFunction: function() {
                      alert("Hello from Scoped UI Script!");
        },
        type: "TestUIScript"
    };
})();

- Then initially keep your code simpler (without validation) and test. Once call is successful, add all validation.
- Add Alert to check where it is not responding.
- For UI script load you can try with ScriptLoader as well

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
// Call the UI script function asynchronously 
g_ui_scripts.getUIScript('x_16799_test.TestUIScript').then(function(result) { 
// Access the function defined in the UI script 
result.dummyFunction(); 
}).catch(function() {
 // Handle cases where the script fails to load 
console.error('x_16799_test.TestUIScript did not load'); 
}); }
