Unable to install required modules

[JannisDev]

With the image ':preloadlibs-latest' i get the error:

Installing modules [ 'otplib@10.2.3' ]
ERROR: Unable to install required modules. MeshCentral may not have access to npm, or npm may not have suffisent rights to load the new module. To manualy install this module try:
cd "/opt/meshcentral"
npm install --no-audit --no-optional --omit=optional otplib@10.2.3
node node_modules/meshcentral

Is there a workaround?
