Write Binary File works only in test steps execution

Hi to all, I want save the first attachment of the email on disk, if I execute with test steps it works like a charm and save the attachment on disk with random name as expected, if I left in execution it is executed but the file is not present on disk and I can’t see any error. Any clues?

thank for your support
Alex

Hey @smilzao,

If you remove the expressions from the path does that work?

When the workflow does run does the execution log show as a success?
