Thank you for your post and I apologize for the delayed response!

Based off your GET https://management.azure.com/subscriptions/<subID>/providers/Microsoft.Authorization/locks HTTP request and error message, it looks like you're missing the lock name at the end of your request GET ...Microsoft.Authorization/locks/{lockName}?api-version=2016-09-01. For more info.

Get At Resource Group Level:

GET https://management.azure.com/subscriptions/subscriptionId/resourceGroups/resourcegroupname/providers/Microsoft.Authorization/locks/testlock?api-version=2016-09-01  

Get At Resource Level:

GET https://management.azure.com/subscriptions/subscriptionId/resourcegroups/resourcegroupname/providers/Microsoft.Storage/parentResourcePath/storageAccounts/teststorageaccount/providers/Microsoft.Authorization/locks/testlock?api-version=2016-09-01  

Get At Subscription Level:

GET https://management.azure.com/subscriptions/subscriptionId/providers/Microsoft.Authorization/locks/testlock?api-version=2016-09-01  

Get By Scope:

GET https://management.azure.com/subscriptions/subscriptionId/providers/Microsoft.Authorization/locks/testlock?api-version=2016-09-01  

I hope this helps!

@Sunil ,

On top of that, as @JamesTran-MSFT pointed out, I also noticed that you posed a similar question on Stackoverflow with the extra detail that you are using azure-sdk in GoLang to access the management API "Microsoft.Authorization/locks" endpoint. The azure-sdk appears to utilize the '2020-05-01' version by default, however this version seems to be not supported by the 'Microsoft.Authorization' namespace.

For further investigation, I've contacted the Azure-SDK and Service team to find out why the Azure-sdk for GoLang uses an unsupported version of the 'Microsoft.Authorization' namespace.

Here is GitHub link for this issue, you can also track the status from: https://github.com/Azure/azure-rest-api-specs/issues/18924

Hope this helps.
