[Issue]: Not able to create a Checkout Payment Session on deployed TEST environment

[mwritter]

Description

Creating an Adyen Checkout Payment session work fine on local development, but Im getting a 401 response with the same setup on the deployed test environment.

Steps to reproduce

1. Install Adyen api-library

npm install --save @adyen/api-library

2. Create a Client and CheckoutAPI payments session

// consts.ts
import { Client } form ''@adyen/api-library"

export const client = new Client({
     apiKey: "API_KEY",
     environment: "TEST"
})

// server.ts
import { CheckoutAPI } form ''@adyen/api-library"
import { client } from "./consts"

export function createSession(request, options) {
   ...
   const checkoutAPI = new CheckoutAPI(client)
   return checkoutAPI.PaymentsAPI.sessions(request, options)
}

Actual behavior

In local development everything is working as expected.

In the deployed test environment the session is returning a 401. Environment variables are the same and set correctly in both local and deployed, and the deployed url is whitelisted in the Customer Area under 'allowed origins'. Any insight into what might be the issue would be greatly appreciated.

Expected behavior

Adyen Checkout Payment sessions can be created the same on both local and deployed test environments.

It looks like the API key is invalid. Are you using the same API key? Is it properly injected in the application deployed on your TEST environment?

@gcatanese - Yeah we did find the issue on our side. The API key was indeed not being set in the docker container we used to build our app. I think this issue can be closed 👍
