retrofit 2 @headers error in kotlin

Braces {} isn't needed inside @Headers.

Use below code:

@Headers(        "Accept: application/json",        "Content-type:application/json")

android kotlin retrofit2

You should use:

@Headers(value = ["Accept: application/json",          "Content-type:application/json"])

because the headers need an array parameter for it, you are using the wrong syntax in kotlin
