node-red-contrib-huemagic -- Error: EPERM: operation not permitted, symlink '../sshpk/bin/sshpk-conv' -> '/data/node_modules/.bin/sshpk-conv'

Error on a docker installed NodeRed
sudo docker run -d --network dockernet --name=nodered -p 1880:1880 -v /home/pi/USBpiData/NodeRed:/data nodered/node-red

checked the permissions are to 755 and uid=1000 gid =1000 (recursive)

also tried this as a fix inside the container:
`INSTALL GLOBAL NPM PACKAGES
npm config set unsafe-perm true

CLEAN CACHE
npm cache clean

BYPASS SYMLINK ISSUES
npm install --no-bin-links`

did not help, here the (still same) error message :-) hope to get help THANKS

`

Start with the Docker command and the mounted /data path described in the issue, then reproduce installation of node-red-contrib-huemagic. Investigate the EPERM symlink creation for /data/node_modules/.bin/sshpk-conv and compare it with the reported permissions and npm settings. Done means identifying a reproducible project-side cause and documenting or testing a fix; the issue does not name a repository file or test.
