Type Cast Issue – Cannot convert the Microsoft.WindowsAzure.Commands Storage.AzureStorageContext

Hello EveryBody,

Hope you all are doing good !!!

Issue :

In my last article, we have seen how to resolve an issue with getting Azure Storage Context . After fixing that issue, when we proceed to create the Stored Access Policy using following coad snippet we face another error of Type Cast as showing here.

New-AzureStorageContainerStoredAccessPolicy -Context $ctx4 -Container “kj-container” -Policy “FourDays-rwdl-Access_KJ-Container” -Permission rwdl -StartTime $StartTime -ExpiryTime $EndTime

Error :

New-AzureStorageContainerStoredAccessPolicy : Cannot bind parameter ‘Context’. Cannot convert the “Microsoft.WindowsAzure.Commands.Storage.AzureStorageContext” value of type
“Microsoft.WindowsAzure.Commands.Storage.AzureStorageContext” to type “Microsoft.Azure.Commands.Common.Authentication.Abstractions.IStorageContext”.
At line:4 char:54New-AzureStorageContainerStoredAccessPolicy -Context $ctx4 -Container …CategoryInfo : InvalidArgument: (:) [New-AzureStorag…redAccessPolicy], ParameterBindingException FullyQualifiedErrorId : CannotConvertArgumentNoMessage,Microsoft.WindowsAzure.Commands.Storage.Blob.Cmdlet.NewAzureStorageContainerStoredAccessPolicyCommand

Solution :

Initially I thought, it is an issue of powershell, because I was using PowerShell 5.1 so I have tested the same coad in PowerShell 7.x and found following different error.

New-AzureStorageContainerStoredAccessPolicy: The ‘New-AzureStorageContainerStoredAccessPolicy’ command was found in the module ‘Azure.Storage’, but the module could not be loaded. For more information, run ‘Import-Module Azure.Storage’.

It means, the command New-AzureStorageContainerStoredAccessPolicy exist under Azure.Storage Module And we are now using Az.Storage module s we need to use relevant command, which exist under Az.Storage module.

Therefore instead of New-AzureStorageContainerStoredAccessPolicy command I used New-AzStorageContainerStoredAccessPolicy command and it works fine and I was able to resolved the type cast issue.

I hope this is informative to you. Please let me know if I missed anything important or if my understanding is not up to the mark.
