"error": {
"code": "VaultNameNotValid",
"message": "The vault name 'ipam-test-kv-2jhngm4kxwuh4' is invalid. A vault's name must be between 3-24 alphanumeric characters. The name must begin with a letter, end with a letter or digit, and not contain consecutive hyphens. Follow this link for more information: https://go.microsoft.com/fwlink/?linkid=2147742"

i recommend either to change naming standard for kv or stop deployment script before bicep deployment mode.
It's not a blocer but nice to have feature ;)
