Summary0021666: Uncaught Error: "Cannot read properties of undefined (reading 'expand_lock')"
DescriptionI have a script which is doing many SQL updates inside one transaction, all of them are executed using await in a sequence. On its end I have something like this:

    if (app.versionBuild >= 2653) {
        await app.db.clearCache();
    }
    // uitools.refreshView(); // doesn't change anything
    var _window = app.dialogs.getMainWindow()._window;
    var coll = app.collections.getCollection(-1);
    _window.nodeUtils.getNodeByPath(_window.currentTabControl.rootNode, [_window.navUtils.createNodeState('root'), _window.navUtils.createNodeState('collection', coll), _window.navUtils.createNodeState('location', coll)]).then(function (oNode) {
        console.log('getNodeByPath: ', (oNode));
        _window.nodeUtils.refreshNodeChildren(oNode, /* withoutProgress: */ true).then(async function () {
            console.log('refreshNodeChildren: ', (oNode));
            // the rest of code
        });
    });

Steps to reproduce:
- start the program with any node selected, except Entire Library > Location node;
- execute script;
- select any node except Entire Library > Location node -> nothing happens for about 25 seconds, i.e. the selected node will not be highlighted, nor the Navigation bar will be updated;
- select Entire Library > Location node -> error;

If I start the program and select the Location node, then I select any other node and execute the script, the error will not happen.

If I change withoutProgress argument to false, the error will not happen (although, the Tree is not responsive for about 25 seconds anyway).

I resolved this using await for both getNodeByPath and refreshNodeChildren.

Tested with the 3162, 2626 (without clearCache) and several other builds in between, with the same result.
