This works  
.body(ByteArrayBody(Array[Byte](10, 9, 112, 100, 18, 16, 112, 95, 105, 110, 115, 116, 97, 108, 108, 97, 116, 105, 111, 110, 73, 100, 25, 124, 69, -73, 94, -45, -51, 71, 64, 33, -77, -20, 73, 96, 115, -107, 94, -64, 41, 0, 0, 0, 0, 0, 0, 0, 64, 48, 1)))

How can i pass feeder file with the following format to request body?  
10, 36, 48, 53, 99, 49, 97, 50, 97, 55, 45, 53, 50, 48, 102, 45, 52, 54, 55, 100, 45, 56, 97, 51, 102, 45, 56, 49, 102, 53, 101, 49, 53, 101, 98, 54, 52, 99, 18, 36, 52, 55, 55, 56, 100, 50, 100, 52, 45, 51, 49, 56, 51, 45, 52, 50, 101, 50, 45, 97, 49, 52, 100, 45, 102, 97, 100, 97, 55, 55, 48, 55, 53, 52, 49, 57, 25, 124, 69, -73, 94, -45, -51, 71, 64, 33, -77, -20, 73, 96, 115, -107, 94, -64, 41, 0, 0, 0, 0, 0, 0, 8, 64, 48, 5  
10, 36, 100, 52, 100, 101, 99, 49, 99, 51, 45, 51, 100, 100, 53, 45, 52, 102, 54, 54, 45, 56, 53, 52, 50, 45, 50, 102, 50, 49, 100, 99, 100, 57, 100, 48, 57, 49, 18, 36, 102, 49, 54, 100, 49, 57, 98, 49, 45, 102, 55, 57, 99, 45, 52, 98, 55, 100, 45, 56, 57, 99, 101, 45, 101, 54, 100, 54, 101, 97, 98, 97, 53, 54, 48, 50, 25, 124, 69, -73, 94, -45, -51, 71, 64, 33, -77, -20, 73, 96, 115, -107, 94, -64, 41, 0, 0, 0, 0, 0, 0, 16, 64
