At a guess, the API has changed and unfortunately, this node has been abandoned: GitHub - dnknth/node-red-contrib-fritzapi: Home automation node for Fritz!Box, Fritz!DECT and FRITZ!Powerline devices.
There is a fork updated 2 weeks ago here: GitHub - Tobi-ctrl/node-red-contrib-fritzapi: Home automation node for Fritz!Box, Fritz!DECT and FRITZ!Powerline devices.
but i dont think it has been published to NPM or the Node-RED catalog however it is still possible to try it.
- stop node red
- cd to
.node-red
dir - uninstall non working node
npm remove Node-red-contrib-fritzapi
- install direct from github using
npm install Tobi-ctrl/node-red-contrib-fritzapi
- start node-red
Worth a go
