Facing issue while calling TableServiceClient using DefaultAzureCredentials() from local environment

**Used the below code

TokenCredential credential = new DefaultAzureCredential();
             TableServiceClient client = new TableServiceClient(
                   endpoint: new Uri("cosmostableuri"),
                   tokenCredential: credential
              );

             var cosmosTable = client.GetTableClient("tablename");
             var entity = cosmosTable.GetEntity<Entity>("partitionKey", "rowkey");

@jahirul2022 It would be great if you could add a link to the documentation you are following for these steps? This would help us redirect the issue to the appropriate team. Thanks!!

I have followed below documentation : [https://learn.microsoft.com/en-us/azure/cosmos-db/table/how-to-dotnet-get-started?tabs=azure-cli%2Cwindows#connect-using-the-microsoft-identity-platform](https://learn.microsoft.com/en-us/azure/cosmos-db/table/how-to-dotnet-get-started?tabs=azure-cli%2Cwindows#connect-using-the-microsoft-identity-platform)https://learn.microsoft.com/en-us/azure/cosmos-db/table/how-to-dotnet-get-started?tabs=azure-cli%2Cwindows#connect-using-the-microsoft-identity-platform

Hi @GeethaThatipatri-MSFT / @YashikaTyagi-MSFT , Please provide some update .

@seesharprun Can you please provide your inputs here

@jahirul2022, I'm checking with the server-side team for the API for Table to see why this error code is being displayed. Based on our documentation and the SDK readme, you should be able to use the DefaultAzureCredential class to create a TableServiceClient or TableClient.

I tried both these blocks of code and got the same error message:

TableServiceClient client = new(
    endpoint: new Uri("https://<account-name>.table.cosmos.azure.com:443/"),
    tokenCredential: new DefaultAzureCredential()
);

TableClient tableClient = new TableClient(
    endpoint: new Uri("https://<account-name>.table.cosmos.azure.com:443/"),
    tableName: "adventureworks",
    tokenCredential: new DefaultAzureCredential()
);

I'll report back once I hear from the SDK or the service team. Thanks!

It looks like this may be a bug with either the SDK or the server-side service. I went ahead and opened a bug in the Azure SDK for .NET repository:

https://github.com/Azure/azure-sdk-for-net/issues/32058

Since we don't have an action item right now in the docs, I will close this issue. I will revisit this issue once we get some feedback from the Azure SDK for .NET team or the service team.

#please-close

We just got a response in the Azure SDK for .NET repo that Azure AD is not supported with Azure Cosmos DB for Table. The how-to guide was errant and the errant section is being immediately removed from the guide. Thank you for your patience.

@seesharprun Thanks for the quick response .
