fromFormat parsing fails on productions, works on development about luxon

The operating system should not matter here, what matters much more is the Node.JS version.

Testing the code you provided with Node 20 fails for me with the error message you've given. The reason for this is that you've provided an invalid locale. Locales should be specified as BCP 47, for Spanish this would be es-ES for example. If you provide an invalid locale, the Intl.DateTimeFormat API (which Luxon uses) falls back to using the system locale. My guess is that your development machines have Spanish configured as the default locale and thus it works there, but not on the production machine.

Hello! You are absolutely right. The locale didn't follow the BCP47 and followed the flow you have described. Thank you very much! I'll close the thread.
