Error while POST obs message

[sidsid14]

I am getting an error when I am sending REST query from mirth's "httpSender" but when I am using the same message in "test" module of openMRS then it is getting accepted. The error is https://pastebin.com/Fk5aanSS

URL: http://localhost:8083/openmrs-standalone/ws/rest/v1/obs

See my answer on your other post: https://talk.openmrs.org/t/post-of-encounter-rest/12560/2?u=darius

I found out that for sending REST request one "needs" to send a request header of Authorization:Basic = username:password or one has to set a cookie of sessionId.
Eg-
URL: http://localhost:8083/openmrs-standalone/ws/rest/v1/visit
METHOD: POST

[HEADERS]
Set-Cookie: jsessionid=C17C12C50D5C194E2487982F08C4BAEB
Authorization:Basic: YWRtaW46QWRtaW4xMjM=

[PARAMETERS]

[CONTENT]
{
"patient":"c342807d-fc65-4de1-983e-424c4add487d",
"visitType":"7b0f5697-27e3-40c4-8bae-f4049abfb4ed",
"location":"bf38803c-b24c-4d54-bd8d-15fe17a79d0d"
