Translate error messages

[felocru]

Hello, does anyone know where the section for translations of error messages is located?
For example: " u'dsds' is not of type 'number' "
The translations that I need to do are for the types, formats, maxLength, etc.
Thank you.

Hi, have a look at e.g. #111 and #20 and let me know if you have any additional thoughts.

Thanks.
