Azure App Service deploy Failed to get resource ID for resource type 'Microsoft.Web/Sites'

Question

In the last 6 months I have been releasing with a pipeline in Azure DevOps, but today I receive the following error:

Answer 1

If your existing service connection is the "Azure Resource Manager using service principal (automatic)" type (not manual), there's a simple but non-obvious way to renew the token.

Go to the service connection's settings page in Azure Devops as described in the other answers. (<YourDevAzureProject> Bottom Left → ⚙️ Project Settings → Pipelines subhead → Service Connections)

Click Edit and then Save without making any other changes. Assuming you have the right permissions, it will automatically get a new token.

NB: for some browsers you must enable pop-ups on dev.azure.com as it attempts to login to your azure account to get a list of resource groups.

(Figured this out from this forum comment.)

Answer 2

From reading others' comments/posts on this thread, the Azure UI might have changed so I'm posting the steps here for the later comers. I did what ecraig12345 suggested and it worked great!

1. Go to the deployment pipeline where the error occurs and click on Edit
2. Go to "Run on agent" task > Deploy Azure App Service
3. Click on the Manage hyperlink next to Azure Subscription label (see screenshot below)
4. Click on Edit
5. Click Save

Steps 1 - 3

Step 4
