Hi all,

When creating the holiday list, it shows Server Error ValueError: expected only letters, got ‘en-gb’ pop up,
how to fix it?

This might be a bug in the way we call holiday list library.

So i should change the language to en_US rather than en_gb?

Can you “copy error to clipboard” and paste the error here?
