Hi,

I'm am developing a new version of my node; however when I test it via the npm link procedure, it shows up in the Palette Manager, but with a strange error and I have no idea how to debug this.

Can anybody provide hints or tips?

Thanks,  
Raimond

Any error in browser console?

You'll need to look at the Node-RED log (not browser console) to see the details.

No errors; I'm looking at the palette code to determine how node listed here are being validated. It seems that node-red itself finds the node invalid.

Strangely, it does work at my local installation on Windows, but it does not on my RPI. Both are node-red version 0.19.5

The console log is also not showing any errors ☹

The Node-RED log _will_ have an entry relating to this node module... it'll be near the start when it first loads the nodes and before your flows are running.

You are right 👍

This is the error, though I still don't get what it is related to..

Also, this error does not occur when I test on windows

I have a workaround for the issue: it was related to some subdependencies with inconsistent versions in de node\_modules. By cleaning out all modules and “npm link” again, the error went away.

Also when installing via the palette, the error does not occur.

So it seems to be a specfic RPi thing.
