Synapse Devops deployment error - service principal expiration

Issue: Deploying code from development environment in synapse to higher environments using Azure Devops failed due to the below error 

Encountered with exception:Error: Get workspace location error: Could not fetch access token for Azure. Verify if the Service Principal used is valid and not expired. For more information refer https://aka.ms/azureappservicedeploytsg

An error occurred during execution: Error: Get workspace location error: Could not fetch access token for Azure. Verify if the Service Principal used is valid and not expired.

Cause: If you are using Azure Devops, you should know that Azure devops needs access to all the environments you are moving code and it uses a service principal to get access to the resources. When your IT admin creates a service principal which is used for Azure Devops, they normally set up a period till when the secret expires. For us we went over the threshold and hence the error. 

Resolution: Asking your Windows AD/IT admin to create a new passcode value and using it in your devops by following below steps

Go to Azure Devops

Navigate to Project Settings > Pipelines > Service Connections and then to edit connection and this opens up a promt as shown below, here update the service prinicpal key you received from your Windows AD/Entra Admin, paste, verify and save it.

Once you have given the new service principal key, we should be ready to start deploying again.
