Error message not proper when invalid token passed to vault-v2, it throws error message "server closed the connection unexpectedly"

create an invalid or dummy TOKEN and pass it to pg_tde_add_key_provider_vault_v2 function.
Then call pg_tde_set_principal_key() it will throw FATAL error message with server termination error message.

Expected: It should throw proper error message without server temnination message.
