Email is not valid although it's a valid email address

Hi there,
I tried to create a new account user with following body:

{
“email":"Test@test.de”,
“name”:“Test”,
“language”:“en”
}

The response is 400 with following message:
The supplied value ‘Test@test.de’ for parameter ‘email’ is not valid

What’s wrong with this email address? It’s a valid email address!

E-mail addresses are usually lowercase only. Maybe that‘s the problem

oh yes this was the problem! But uppercase should not be a problem, it’s still a valid email address… :wink:

The standard defines them as lower case only, but most systems tolerate uppercase and convert them somewhere in the delivery process. Therefore you better convert them in your frontend to lowercase so that you can prevent any problems.
