Symfony version(s) affected: 5.2 (symfony/uid + symfony/form)

Description
Hello,

I am using the newly shipped uid component 🚀 (great work btw) and implementing tests.

I have :

• a Product with a uuid as a primary key
• a form type having a product field which is an EntityType

When I submit the form with an invalid uid, it throws an exception causing a 500 which is not really friendly.

How to reproduce

Possible Solution
Would it be possible to have the same behaviour as any other choicetype so that we can have a 400 with an invalid error message ?

Additional context
