Unable to create CosmosClient instance when using version 3.3.0 - dotnetcore 2.2 console app

Describe the bug When creating an instance of Microsoft.Azure.Cosmos.CosmosClient in a dotnetcore 2.2 console application an exception is thrown from the CosmosClient constructor. This is only an issue with Microsoft.Azure.Cosmos version 3.3.0, version 3.2.0 works as expected.

            using (CosmosClient client = new CosmosClient(endpoint, authKey))
            {
            }

Stack Trace shows an FormatException being thrown from the DocumentClient.Initialize method when configuring some http headers.

Stack Trace Unhandled Exception: System.FormatException: The format of value ‘18.7.0: Tue Aug 20 16:57:14 PDT 2019; root:xnu-4903.271.2~2/RELEASE_X86_64/X64 3.3.0/3.3.0-.NET Core 4.6.27817.03 89710’ is invalid. at System.Net.Http.Headers.HttpHeaderParser.ParseValue(String value, Object storeValue, Int32& index) at System.Net.Http.Headers.HttpHeaders.ParseAndAddValue(HeaderDescriptor descriptor, HeaderStoreItemInfo info, String value) at System.Net.Http.Headers.HttpHeaders.Add(HeaderDescriptor descriptor, String value) at Microsoft.Azure.Cosmos.DocumentClient.Initialize(Uri serviceEndpoint, ConnectionPolicy connectionPolicy, Nullable1 desiredConsistencyLevel, HttpMessageHandler handler, ISessionContainer sessionContainer, Nullable1 enableCpuMonitor, IStoreClientFactory storeClientFactory) at Microsoft.Azure.Cosmos.DocumentClient…ctor(Uri serviceEndpoint, String authKeyOrResourceToken, EventHandler1 sendingRequestEventArgs, ConnectionPolicy connectionPolicy, Nullable1 desiredConsistencyLevel, JsonSerializerSettings serializerSettings, ApiType apitype, EventHandler1 receivedResponseEventArgs, HttpMessageHandler handler, ISessionContainer sessionContainer, Nullable1 enableCpuMonitor, Func`2 transportClientHandlerFactory, IStoreClientFactory storeClientFactory) at Microsoft.Azure.Cosmos.CosmosClient…ctor(String accountEndpoint, String authKeyOrResourceToken, CosmosClientOptions clientOptions)

To Reproduce Create a new dotnetcore 2.2 console application. Add a reference to a Microsoft.Azure.Cosmos v3.3.0. Attempt to create an instance of the CosmosClient class using a valid endpoint and api key.

Expected behavior The CosmosClient instance is created.

Actual behavior An exception is thrown and the CosmosClient instance is not created.

@ctrlaltdan are you sure you updated to 3.3.2? Can you try deleting the bin and obj folders and making sure you aren’t using a cached version. The user agent string in the error message says it’s version 3.3.0

[j82w]

Yeah, that’s why the change log specifies non-windows.
