为什么我收到 PayPal Android Native Checkout SDK - 无效的 client_id 或 redirect_uri

我正在使用新的 Android Native Checkout SDK 和 Kotlin，并且我一直遵循文档中的每一步，但这种情况不断发生，我不知道为什么。我也在尝试PayPal Android Native Checkout SDK - 无效的 client_id 或 redirect_uri 以及 CHECKOUT_ERROR https://stackoverflow.com/questions/66380972/paypal-android-native-checkout-sdk-invalid-client-id-or-redirect-uri-and-chec但这对我不起作用。
