Question

Hi,
In our company we frequently use this task to deploy a bicep and bicepparam towards our Azure Cloud environment(s). Now I was digging through and following the code where eventually the following code caught my eye:
https://github.com/microsoft/azure-pipelines-tasks-common-packages/blob/626b27c67dcbc98a222c3ed13d47903107e8f44a/common-npm-packages/azure-arm-rest/AzureServiceClientBase.ts#L174

For example we have a small bicep running via this task only doing some existing(/reference) since we want to know hostnames. That one takes on its own in the Deployments-tab not even 1 second, but in my Azure DevOps Server (on-premise) Pipeline about 40 seconds and thus significantly (relatively) slowing down stuff. Even on larger biceps which really does stuff, we also see way longer running tasks in ADO compared to the Deployments-tab in Azure.

Is there any reason for such a big wait, could it be lower or could we even by start/first rely on the retry-after? Although mostly I see the 15-second.

The reason I am using this task is that we have seen it in ymls presented by ADO when creating one based on a dotnet api, we are a software development company, in a repo. If there are perhaps better/other/different ways I am open to it.
