How to Clear history just one log of script??

Your code doesn't work for me, even before it is placed in the function. What are the conditions required to make it run? Just an active selection?

This is what I meant:

function myScript() {
    
// Your code here

}
app.activeDocument.suspendHistory("Run script", "myScript()");

As in:

function myScript() {
    cTID = function (s) {
        return app.charIDToTypeID(s);
    };
    sTID = function (s) {
        return app.stringIDToTypeID(s);
    };
    function ContentAware() {
        // Expand
        function step1(enabled, withDialog) {
            if (enabled != undefined && !enabled)
                return;
            var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
            var desc1 = new ActionDescriptor();
            desc1.putUnitDouble(cTID('By '), cTID('#Pxl'), 2);
            desc1.putBoolean(sTID("selectionModifyEffectAtCanvasBounds"), false);
            executeAction(cTID('Expn'), desc1, dialogMode);
        };
        // Fill
        function step2(enabled, withDialog) {
            if (enabled != undefined && !enabled)
                return;
            var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
            var desc1 = new ActionDescriptor();
            desc1.putEnumerated(cTID('Usng'), cTID('FlCn'), sTID("contentAware"));
            desc1.putBoolean(sTID("contentAwareColorAdaptationFill"), true);
            desc1.putBoolean(sTID("contentAwareRotateFill"), false);
            desc1.putBoolean(sTID("contentAwareScaleFill"), false);
            desc1.putBoolean(sTID("contentAwareMirrorFill"), false);
            desc1.putUnitDouble(cTID('Opct'), cTID('#Prc'), 100);
            desc1.putEnumerated(cTID('Md '), cTID('BlnM'), cTID('Nrml'));
            executeAction(cTID('Fl '), desc1, dialogMode);
        };
        // Set
        function step3(enabled, withDialog) {
            if (enabled != undefined && !enabled)
                return;
            var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
            var desc1 = new ActionDescriptor();
            var ref1 = new ActionReference();
            ref1.putProperty(cTID('Chnl'), sTID("selection"));
            desc1.putReference(cTID('null'), ref1);
            desc1.putEnumerated(cTID('T '), cTID('Ordn'), cTID('None'));
            executeAction(cTID('setd'), desc1, dialogMode);
        };
        step1(); // Expand
        step2(); // Fill
        step3(); // Set
    };
    //=========================================
    // ContentAware.main
    //=========================================
    ContentAware.main = function () {
        ContentAware();
    };
    ContentAware.main();
    // EOF
    "ContentAware.jsx"
    // EOF
}
app.activeDocument.suspendHistory("Run script", "myScript()");

@Stephen Marsh  Thanks for reply...
Hmm... I think it's in parentheses, but there's an error. Am I an Stupid...?

function main () {
alert(
cTID = function(s) { return app.charIDToTypeID(s); };
sTID = function(s) { return app.stringIDToTypeID(s); };

function ContentAware() {
// Expand
function step1(enabled, withDialog) {
if (enabled != undefined && !enabled)
return;
var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
var desc1 = new ActionDescriptor();
desc1.putUnitDouble(cTID('By '), cTID('#Pxl'), 2);
desc1.putBoolean(sTID("selectionModifyEffectAtCanvasBounds"), false);
executeAction(cTID('Expn'), desc1, dialogMode);
};

// Fill
function step2(enabled, withDialog) {
if (enabled != undefined && !enabled)
return;
var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
var desc1 = new ActionDescriptor();
desc1.putEnumerated(cTID('Usng'), cTID('FlCn'), sTID("contentAware"));
desc1.putBoolean(sTID("contentAwareColorAdaptationFill"), true);
desc1.putBoolean(sTID("contentAwareRotateFill"), false);
desc1.putBoolean(sTID("contentAwareScaleFill"), false);
desc1.putBoolean(sTID("contentAwareMirrorFill"), false);
desc1.putUnitDouble(cTID('Opct'), cTID('#Prc'), 100);
desc1.putEnumerated(cTID('Md '), cTID('BlnM'), cTID('Nrml'));
executeAction(cTID('Fl '), desc1, dialogMode);
};

// Set
function step3(enabled, withDialog) {
if (enabled != undefined && !enabled)
return;
var dialogMode = (withDialog ? DialogModes.ALL : DialogModes.NO);
var desc1 = new ActionDescriptor();
var ref1 = new ActionReference();
ref1.putProperty(cTID('Chnl'), sTID("selection"));
desc1.putReference(cTID('null'), ref1);
desc1.putEnumerated(cTID('T '), cTID('Ordn'), cTID('None'));
executeAction(cTID('setd'), desc1, dialogMode);
};

step1(); // Expand
step2(); // Fill
step3(); // Set
};

//=========================================
// ContentAware.main
//=========================================
//

ContentAware.main = function () {
ContentAware();
};

ContentAware.main();

// EOF

"ContentAware.jsx"
// EOF);
}
app.activeDocument.suspendHistory("Run script", "main()");

The first code snippet in the following link will do that, just insert your action converted code inside the function braces, replacing the placeholder alert()
