Azure Media Services v3 Assets.ListContainerSasAsync returns ApiErrorException

Question

I'm calling Assets.ListContainerSasAsync from Azure Media Services v3 in (.net), however, APIErrorException is returned with no apparent reason. I've triple-checked I've got valid config.ResourceGroup, config.AccountName, and assetName parameters.

Code:

AssetContainerSas assetContainerSas = await client.Assets.ListContainerSasAsync(config.ResourceGroup, config.AccountName, assetName, permissions: AssetContainerPermission.Read, expiryTime: DateTime.UtcNow.AddYears(1).ToUniversalTime());

Exception:

Answer 1

The issue is likely related to the expiry time. According to https://learn.microsoft.com/en-us/rest/api/media/assets/listcontainersas#request-body the expiryTime must be less than 24 hours. For long lived SAS URLs, please use the Storage API.
