[BUG] Create of of async client fails with assertion error on Cosmos SDK v4

Describe the bug Using the Cosmos SDK v4, I attempt to create a client using CosmosClientBuilder. Both CosmosClientBuilder.buildAsyncClient() and CosmosClientBuilder.buildClient() fail with an assertion error.

Exception or Stack Trace Assertion fails due to globalEndpointManager.getLatestDatabaseAccount() returning null during initialization:

java.lang.AssertionError
	at com.azure.cosmos.implementation.RxDocumentClientImpl.initializeGatewayConfigurationReader(RxDocumentClientImpl.java:264)
	at com.azure.cosmos.implementation.RxDocumentClientImpl.init(RxDocumentClientImpl.java:282)
	at com.azure.cosmos.implementation.AsyncDocumentClient$Builder.build(AsyncDocumentClient.java:204)
	at com.azure.cosmos.CosmosAsyncClient.<init>(CosmosAsyncClient.java:98)
	at com.azure.cosmos.CosmosClientBuilder.buildAsyncClient(CosmosClientBuilder.java:649)
...

To Reproduce Run the following code snippet. The code is executed during a test, while invoking it from @Test and @BeforeClass does not make a difference.

Code Snippet

new CosmosClientBuilder()
    .endpoint(ENDPOINT)
    .key(KEY)
    .buildAsyncClient();

Expected behavior Client is created successfully and can be used to create database and container objects.

@JanneKataja-TomTom - closing this issue since the key used was incorrect, hopefully it works fine with the right key 😃

It appears this bug was fixed as a part of #14742

Also, in case the domain name is incorrect, the exception is not thrown but instead the following error is logged in a loop:
