When a take a picture a function returns time/date. . The function return this output _msg.filename : string[42]_ _"/home/pi/Pictures/cam3\_20220214-130253.jpg"_. In the Exec node, I currently have this settings -w 800 -h 600 -o ~/Pictures/test\_image.jpg ....  
I want to use this string withe the date/time as filename in Execl. I trided {{msg.filename}}, but with no success. Any suggestions?

What is the Raspistill node? I can't find it in the flows library.

Sorry for confusing ... it's the Exec node ... someone call it Raspistill, that's how it was mentioned as that ...

You could try setting msg.filename to `-o /home/pi/Pictures/cam3_20220214-130253.jpg` ie including the -o  
And in the exec node tick Append. Change "payload" to "filename"

</div>

Where is the error 126 coming from?Node-Red? Excel?  
Is there more information than just 126?

Have you tried attaching a debug node (set to display the complete msg object) to each of the outputs of the `exec` node?
