I am trying to read streaming data from EventHub which is in JSON Format, able to read data in a data frame but the body type was coming as binary I have converted it to string and decoded but while implementing the write stream I am facing an ongoing error as follows: 

terminated with exception: Illegal base64 character 7b SQLSTATE: XXKST and another error as Input byte array has wrong 4-byte ending unit
It also does not accept a JSON input array. I have also tried implementing UTF-8 and base64 decoding logic, but it didn't work.
