We have noticed a few errors in our system where the response for the EnvelopeLocks:get endpoint (https://developers.docusign.com/docs/esign-rest-api/reference/envelopes/envelopelocks/get/) does not contain the lockToken field.
The docs dont seem to have any point which indicates this as expected behaviour.
Wanted to know if there is some nuance I am missing?

btw we get all the other data about the lock in the response, its just the lockToken that is not there:
 

{
 lockedByApp: "-",

 lockedByUser: {
  uri: "--------------",
  userId: "--------------------",
  userName: "------------------"
 },
 lockedUntilDateTime: "--------------------",
 lockType: "------"
}
