If you create a user without a first or last name directly in keycloak, the api returns a 500

[olevski]

When you create a user directly in keycloak you dont have to put in a first or last name.

Then the user gets immediately synced with the DB.

And then the api endpoint that gives the user info fails with a 500 because the first and last name have to have at least 1 character.

And for that user the platform is completely unusable. Because the ui considers renkulab to be down if the backend responds with a 500 when the user is listed.

We need to gracefully handle this case. Because we do not control how Keycloak validates new user creation.

I cannot reproduce: I have created 2 users, one with only a first name and one with only a last name and both can use Renku (on a CI deployment).
