I want to add the icon & change the text color to Red on condition.But getting the error-'Error retrieving data TypeError: Cannot add property statucBadgeColor, object is not extensible'.

Please find the JS code for LWC-

const PARTNERTASKCOLUMN = [
{label: columnHeader1,
    type: 'text',
    hideDefaultActions: true,
    fieldName: 'Name',
    // typeAttributes: {label: {fieldName: 'offeringTitle'}, target: '_self'},
    sortable: true
},
{label: columnHeader3,
    type: 'text',
    hideDefaultActions: true,
    fieldName: 'Status__c',
    sortable: true
}
{label: columnHeader5,
    type: 'date',
    hideDefaultActions: true,
    // fieldName: 'Due_Date__c',
    sortable: true,
    typeAttributes: {
        value: { fieldName: 'Due_Date__c' },
        iconColor: { fieldName: 'statusBadgecolor' },
        icon: { fieldName: 'statusIconName' },
        textColor: { fieldName: 'statusBadgecolor' }
    }
}
