While working on LSST multi-object search, I found that the multi-object search in IRSA viewer does not work.

After spending hours to look into the reason, I found that the uploaded table in CatalogSelectViewPanel.jsx is not proper defined.

  if (spatial === SpatialMethod.get('Multi-Object').value) {

        var filename = get(catPart, 'fileUpload');

The correct way should be:

if (spatial === SpatialMethod.get('Multi-Object').value) {

        var filename = get(spacPart, 'fileUpload');
