BE2: No error displayed when a client fails to create

[chrisvire]

In BE1, if you try to create a client, it won't let you enter more that 4 characters for the prefix.
In BE2, there is no limit, but clicking Create does nothing if there are more than 4 characters.

I see this in the browser log:

fetcher.js?v=52872927:66
POST http://localhost:8443/client-admin/create 500 (Internal Server Error)

This is in the server console:

[500] POST /client-admin/create
PrismaClientKnownRequestError:
Invalid `prisma.client.create()` invocation:


The provided value for the column is too long for the column's type. Column: (not available)
