Hitting from Postman API to nav 2013 r2 service order

need help, recently I have been working on a service order where I'm facing 500 error when trying to hit through postman to nav 2013 r2.

Note: Service order contains select job types with mapping fields based on general job category and job type. The error you can see also has the same content in JOB TYPE MASTER

Body of postman Api:
