Hello Community

I want to generate a pdf in node red and want to enter the file name (and maybe the location) with variables. I heard that this could work with the msg.filename, but I couldn't find anything. can someone help me?

remove the hard coded filename from the file node & in your function add something like...

// your code
const reportDate = new Date().toISOString().replace(/[TG]/g,'_').replace(/:/g,'-').substring(0,19);
const reportName = 'mydata'
msg.filename = `c/reports/report-${reportName}-${reportDate}.pdf`
return msg;

If you post code/flow instead of pictures I can show you.

PS...

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 ```)

``` 
   code goes here 
```

See this post for more details - How to share code or flow json
