ERROR

jstree.min.js:1559 Uncaught TypeError: Cannot read properties of undefined (reading 'call') at a.jstree.plugins.wholerow.k (jstree.min.js:1559:27) at a.jstree.plugins.wholerow. (jstree.min.js:1579:27)

I can log the data meaning I am getting json data from service I can't append it to selected node

This is not what _append_json_data is supposed to do - it is an internal function - do not use it to add data yourself.
