Server error while performing a GET to the v1/me/player/recently-played endpoint

[truebelief]

I'm trying to perform a request to the 'v1/me/player/recently-played' endpoint in a Kotlin Ktor client application (code snippets below, but the same happens in Postman). The interesting fact is that if i use the Bearer token gotten from the API docs, from the try it section, it works.

I'm successfully getting the accessToken by doing this:

val clientCredentials =
    "clientId:clientSecret".toByteArray().encodeBase64()
val token = client.post<String>("https://accounts.spotify.com/api/token") {
    header(HttpHeaders.ContentType, ContentType.Application.FormUrlEncoded.toString())
    header(HttpHeaders.Authorization, "Basic $clientCredentials")
    body = "grant_type=client_credentials&scope=user-read-recently-played"
}

And then, the actual call to the aforementioned endpoint:

val decodedToken = Json.decodeFromString<Token>(token)
val response = client.get<String>("https://api.spotify.com/v1/me/player/recently-played") {
    accept(ContentType.Application.Json)
    header(HttpHeaders.Authorization, "Bearer ${decodedToken.accessToken}")
}

I end up getting:

{

"error": {

    "status": 500,

    "message": "Server error."

    }

}

I'm having same problem with Python, did you get to manage this by yourself? thanks
