Is it possible posting request bytearray without error 500,400?


I was able to post request as base64 and received answer without error. Than I switched my method having images converted bytearray instead of base64. Now İ can not receive success. What İ have tried was to update my script removing base64 convertion and put bytearray instead. I am using post method with binary and upload my image on postman. I received 500 error. Is there another way to try it?
