Im trying to deploy a nuget package to an azure webapp,but this fails sometimes and succeeds sometimes.

sometimes the error is
System.AggregateException: One or more errors occurred. —> Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: Cannot perform runtime binding on a null reference


We have received quite a few support cases with the same error, and it seems there was an outage in Azure that caused this issue, see
We actually got some customers reporting it via our slack channel as well, see

So it seems Azure is all good now, are you able to retry these deployments ?
