from the attached image i can say your curl command should be in one single line(can include space not enter)
curl -X POST http://192.168.1.83:8080/jsonrpc -H ‘Cache-Control: no-cache’ -H ‘Content-Type: application/json’ -H ‘Postman-Token: 82ec87fb-667f-a0fe-182e-9621199274ae’ -d ’ {“jsonrpc”: “2.0”, “method”: “Input.Up”, “id”: 1}’
