  1. That's not valid JSON. The "profilePhoto" you are sending is numbers with letters. That's not a valid type. It can be either a number or a string. If it is to be a string, then wrap it in " quotes.

  2. After you make it a valid string, the deserializer doesn't know how to map the string to a byte[]. You will need to create a custom (de)serializer. With MOXy, you can use an XmlAdapter. An example would something as simple as

    import javax.xml.bind.annotation.adapters.XmlAdapter;
import java.util.Base64;

public class Base64ByteArrayAdapter extends XmlAdapter<String, byte[]> {

    @Override
    public byte[] unmarshal(String base64) throws Exception {
        return Base64.getDecoder().decode(base64);
    }

    @Override
    public String marshal(byte[] bytes) throws Exception {
        return Base64.getEncoder().encodeToString(bytes);
    }
}

    The unmarshal will handling converting the incoming base64 string to a byte[], and the marshal will handle the converting of the byte[] to the base64 string.

    Then you just need to annotate the property in the bean with the adapter

    @XmlJavaTypeAdapter(Base64ByteArrayAdapter.class)
public byte[] getProfilePhoto() {}
