Replicating Tutorial to Build out End-to-End Solution and am unable to authenticate using ManagedIdentityCredential

Question

I have followed every step of this tutorial: [tutorial-end-to-end]

However, when I try and create the building scenario using the command, SetupBuildingScenario, I am unable to authenticate because of an error with ManagedIdentityCredentials. I feel like I am supposed to be using DefaultAzureCredential but it is defaulting to the other method. I have tried switching the version of Azure.Identity from 1.3 to1.2.3 but still nothing has worked. I am attaching the error log below.

Answer 1

I was able to solve the issue. After figuring out the order that DefaultAzureCredential attempted to authenticate, I excluded attempts to ManagedIdentityCredential and SharedTokenCacheCredential. This looked like:
var credential = new DefaultAzureCredential(new DefaultAzureCredentialOptions { ExcludeManagedIdentityCredential = true, ExcludeSharedTokenCacheCredential= true })

Now I am able to replicate the tutorial!

Answer 2

@afdelacruz Thanks for the details. I have followed the documentation as is and able to complete it successfully.

I would suggest you, please recheck Set up local Azure credentials again and see if you are missing any steps.

Also, please ensure to assign the Azure Digital Twins Data Owner role using the access control options in Azure Identity Management(IAM).

First see if you have the correct role assignment by checking access.

Goto your ADT -> Access Control -> Check access

If not, please follow the steps Assign the role using Azure Identity Management (IAM) and verify the role assignment success.

Hope this helps to resolve your issue. Please let me know if you need any further help.
