Bug description:

The validation messages are not displayed in the editors when inputting an invalid value.

Expected behavior:

When a field is invalid, the field should become red and display the validation message from the JSONschema.

Steps to Reproduce:

1. Go to create a new item
2. Input a barcode that already exists
3. The field becomes red but there is no message to tell us why (alreadyTakenMessage)
4. Add a field "URL" and input "toto"
5. The field becomes red but there is no message to tell us why (patternMessage)
6. etc.

Context
