again I spend over 2 hours to debugging.
The Package "node-red-contrib-powershell" has a bug. The msg.payload will not correct returned.
In github the error is corrected, see: node-red-contrib-powershell/powershell.js at master · tobiassoltermann/node-red-contrib-powershell · GitHub
The correction was 12 Dec 2019!
Please guide me in the right direction. Is it wrong to use the Packages which I can install with the "add palette" button?
And how did you work?
Spend hours and hours and analyse the sourcecode seams a bit time consuming for me.
