formatDate(addDays(now;1);"EEE") always returns "555" in Tools module

Hi everyone :waving_hand:
I’ve encountered a strange behavior when using the following expression inside a Tools → Set variable or Set multiple variables module:

formatDate(addDays(now; 1); "EEE")

Instead of returning a weekday abbreviation (like Fri, Sat, etc.), the output is always "555".
This happens in every scenario execution (100% reproducible).
The expression chips (formatDate, addDays, now) are recognized correctly, but the evaluated value is wrong.

:white_check_mark: Tested:

  • Works fine with "YYYY-MM-DD" and other formats.

  • Affects only "EEE" (maybe "EEEE" as well).

  • Tested in multiple scenarios and accounts.

Has anyone else run into this?
Is it a known limitation or a parsing issue inside the Tools module?

Thanks in advance :folded_hands:

Hey there,

its ddd not EEE. Tokens for date/time formatting - Help Center

E gives you day of the week as a number. So EEE will give it three times in a row. For Friday - 555
