@s1nbad Welcome to the forum Peter!
- What version of Node-RED and node.js are you running? (you can get these from the start up log)
- Can you export* and attach a small sample flow showing the issue? That will make it easier for people to help you.
* In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote ```)
```

You can edit and correct your post by clicking the pencil 
icon.
