Create file with variable name under 0.19.4

General

Hello everyone,

does anyone know how I can assign a file name with a variable in Node-Red version 0.19.4.
I want to write a file with a dynamic file name that contains the date.
The variable works, I can read it with debug and see it among the variables. For example: g_filename: xyz_2025-04-09.txt
If I enter the variable in the file node, the file is created with the variable name 'g_filename' and not with the generated variable 'xyz_2025-04-09.txt'.
In the newer versions this works without problems. Does anyone know the trick in the old version 0.19.4?
Oh yes .... an update is not an option :wink: true to the motto: never touch a running system!!!

Thanks already
Roland

what does the nodes built in help say?

Inputs

filename string
if not set in the node configuration, this property sets the filename to read.

i.e. leave it blank, ensure your file name is set in msg.filename

the system has no external access,
I use it to control my heating and a few other things.

But you can never be sure! :roll_eyes: :see_no_evil_monkey:
