@Multipart
@Headers("Content-Type: application/json")
Call<SignUpResponse> signUp(
        @Part MultipartBody.Part profilePicture,
        @Query("email") String email,
        @Query("password") String password,
        @Query("firstName") String firstName,

    All what I did to fix my problem was remove this Annotation

    @Headers("Content-Type: application/json")

    from my code and request.
    and for sending empty files you can just send a null parameter for file will take it as empty.

    You can use @Part("email") RequestBody email, rather than @Query .

    @POST(SIGN_UP_USER)
@Multipart
Call<SignUpResponse> signUp(
        @Part MultipartBody.Part profilePicture,
        @Part("email") RequestBody email,
        @Part("password") RequestBody password,
        @Part("firstName") RequestBody firstName,
        @Part("lastName") RequestBody lastName);

RequestBody email= requestBody1.create(MediaType.parse("text/plain"), "[email protected]");

    Try the below way. [I’m using Kotlin].

    1. Create Multipart Body Object

               val signUpBuilder = MultipartBody.Builder().setType(MultipartBody.FORM)
         signUpBuilder.addFormDataPart("email",email)
         signUpBuilder.addFormDataPart("password",password)
         signUpBuilder.addFormDataPart("firstName",firstName)
         signUpBuilder.addFormDataPart("lastName",lastName)
         signUpBuilder.addFormDataPart("profilePicture","filename.jpg",file)
         signUpBuilder.build()

    2. Pass the builder to your signup method.

    Do not use multipart annotation.

    @POST(SIGN_UP_USER)
fun signUp(
    @Body requestBody: MultipartBody
): Call<SignUpResponse>

    Hope this will help you.
