hey @alexcos20
in case ANY check of the above fails BUT the DDO object is still VALID should we:

• return a 200 msg anyway (but without adding the node signature)
• just return a 400 error (validation failed)

Example; lets say we did not sent one of the optional parameters..

In any case we need to change the SDK as well (current /ddo/validate response on the SDK is handled this way:)

if (response.status === 200) {
        status.valid = true
        status.hash = jsonResponse.hash
        status.proof = {
          validatorAddress: jsonResponse.publicKey,
          r: jsonResponse.r[0],
          s: jsonResponse.s[0],
          v: jsonResponse.v
        }
      }

(so, if 200 it assumes we have a signature)

But we're not sending the optional parameters on the /ddo/validate request... we're just sending the DDO ..

const response = await fetch(path, {
        method: 'POST',
        body: JSON.stringify(ddo),
        headers: { 'Content-Type': 'application/octet-stream' },
        signal
      })

So, we need to change something there in any case, either on the request (add the params) or on the way we handle the response...

thanks
