[Abhishek Kini]

 Hi,

I  created a patient and tried to POST an observation which was actually an observation of another patient in the Cerner itself but showing 422 Unprocessable entity issue.

X-request-id -  0aad0fa2-617d-4bf8-bcc0-22d23a6a7fa3 

The Body is shown below:

            "code": "invalid",

Can anyone help on this?

Hello,

Patient 12770316 does not have any Encounter and hence you are not able to post the Observation. Please use any other patient, example: 12742400

Also, the code for unit of measure seems to be incorrect. Please use

"system": "http://unitsofmeasure.org",

"code": "{Breaths}/min"

Thanks,

Fenil
