with react & react-dom version ^18.2.0

TypeError Cannot read properties of null (reading 'scrollToIndex') in

Hello! I just checked it on my end and I don't have any issues.

Can you provide a sandbox example with the issue reproduced?

[agupta-mv]

When the react sortable tree is mounted and when clicked on tree node, thats when the issue occurs.
Also we havent passed virtuosoRef to react sortable tree.
As we havent passed virtuosoRef prop, there should not be any need of scrollToIndex from this.listRef.
This issue doesnt occur frequently but once in 5 times.
We have attached video demonstrating the occurence of issue.

if (searchFocusTreeIndex !== undefined) {
this.listRef.current.scrollToIndex({
index: searchFocusTreeIndex,
align: 'center'
});
}

can u add scrollToIndex check in the above if condition.

Should be fixed in v5, but it's still in alpha.

npm i @nosferatu500/react-sortable-tree@5.0.0-alpha.5
