index is undefined in SortableElement v 0.4.10

See original GitHub issue

Hello, I updated to version 0.4.10 and now when I try to access index prop inside my SortableElement it is undefined, in the meantime I will return to previous version where everything is fine.

const SortableItem = SortableElement((props) => {
    const {name, fields, index} = props;
    if(fields.get(index).type == 'error'){
            <div className="file-upload-file-container file-container-error">

    } else{
        return (
            <div className="file-upload-file-container">


const SortableList=SortableContainer(({fields, onDeleteItem})=>{
    return (
        <div className="">
            {, index, fields) => {

Why was this closed? This is some pretty janky behavior that at the very least should be documented. Thought I was going crazy until I realized it’s a bug in this library. Ended up taking your suggestion @clauderic of passing the index as a separate prop.

I also ran into this problem and was very confused until finding this issue. I’ve implemented the work around of passing the index as an additional separate prop, but I agree with others that this feels unintuitive maybe not the best behavior.
