Describe the issue/error/question

Hello!

I am trying to upload a txt file to Nextcloud using a base64 encoded string as source, and decoding it before the save. But it ends being an blank line in the file.

My expression looks like:

{{ atob("SGVsbG8gV29ybGQh") }}

Test

The function finishes successfully but the txt file only contains the Test line:



Test

The interesting thing is that I can see the output correctly decoded in the expression preview window.
So the issue is only when running the workflow.

What is the error message (if any)?

None

Try with {{Buffer.from("SGVsbG8gV29ybGQh", 'base64').toString()}} instead.
