    I don't see why you would get that error, but you should be doing myFunction={this.myFunction} and myFunction={this.props.myFunction}:

    class SomeComponent extends Component{
    
        constructor(props){
            super(props);
            //does whatever stuff        
            this.myFunction = this.myFunction.bind(this);
    
        }
    
        //(only applicable to raw and normal forms)
        myFunction(param){
            console.log('do something: ', param);
        }
    
        render(){
         return (
    ) } } class ChildComponent1{ render(){ return (
    ) } } class ChildComponent2{ render(){ return () } }

    Wrapping the function call inside another (arrow) function is just unnecessary and won't forward the parameter properly (since all your intermediate arrow functions do not accept a parameter).
