@edwardmedia I don't think the field can be updated. I tried it in API explorer and got the response:

{
  "error": {
    "code": 400,
    "message": "Invalid value for field 'resource': '{  \"fingerprint\": \"KN4X1G0qzB0=\",  \"purpose\": \"INTERNAL_HTTPS_LOAD_BALANCER\"}'. The following field(s) specified in the request cannot be modified: [purpose]",
    "errors": [
      {
        "message": "Invalid value for field 'resource': '{  \"fingerprint\": \"KN4X1G0qzB0=\",  \"purpose\": \"INTERNAL_HTTPS_LOAD_BALANCER\"}'. The following field(s) specified in the request cannot be modified: [purpose]",
        "domain": "global",
        "reason": "invalid"
      }
    ]
  }
}

Closing this since I think there's nothing to do here.
