Steps to reproduce

1. Generate a csr using openssl openssl req -newkey rsa:2048 -keyout PRIVATEKEY.key -out MYCSR.csr
2. cat MYCSR.csr
3. Send that csr in a createCertificate request:

  return await client.createCertificate({
    parent: '/path/to/pool',
    certificate: {
      name: 'my cert',
      lifetime: {
        seconds: 31536000, // 1 year
      },
