Npm update error "Cannot convert undefined or null to object"

When running "npm update" in my ./.node-red directory I get the error "Cannot convert undefined or null to object". The Idealtree seems to run to completion. The error log looks like this:

Node-RED version : 3.0.2
Node version v16.17.0
Raspberry pi 4

This happened after upgrading Node-RED and Node.js to the latest version. I had run "npm update" before that without any issue. When I update nodes through the graphical interface, that works fine without any problem. Does anyone have a suggestion on how to get rid of this error?

I fixed the issue by moving my .node-red directory to a safe place, then restarting node-red. Then I copied everything except the node_modules directory and the pakage.json file to the new .node-red directory. After another restart of node-red, it started complaining about all the missing modules. I installed those by hand , using npm. Restarting node-red and running npm update once in a while during this proces. In the end, all was ok and things are working again.
