Listing all apps with App Store Connect API returns error ENTITY_INVALID

Question

I'm using this code to get all apps in App Store Connect:

let jwt = ...
var request = URLRequest(url: URL(string: "https://api.appstoreconnect.apple.com/v1/apps")!)
request.setValue("Bearer \(jwt)", forHTTPHeaderField: "Authorization")
let session = URLSession(configuration: .ephemeral)
let task = session.dataTask(with: request) { data, response, error in
    if let error = error {
        print(error)
    } else if let data = data {
        print(String(data: data, encoding: .utf8))
    }
}
task.resume()

But the response is an error status: 400, code: ENTITY_INVALID, title: JSON processing failed. What entity is this error referring to? And what JSON is invalid? The JWT token seems to be fine, since when using a random value I get an error 401 NOT_AUTHORIZED.

In my case, I was including an empty array for the scope member of the claim portion of the JWT. If no scope is needed, do not include that member at all — Dave Nottage

Thanks! That seems to be the reason. You may want to add this as an answer. — Nickkk

As per my comment in the question, if no scope is required, you need to omit it from the claim portion of the JWT, i.e. instead of (for example):

{
    "iss": "57246542-96fe-1a63-e053-0824d011072a",
    "iat": 1528407600,
    "exp": 1528408800,
    "aud": "appstoreconnect-v1",
    "scope": [
    ]
}

Use:

{
    "iss": "57246542-96fe-1a63-e053-0824d011072a",
    "iat": 1528407600,
    "exp": 1528408800,
    "aud": "appstoreconnect-v1"
}
