Trying to copy file within same Storage account causing Could not verify copy source exception

Question

Trying to copy file within same Storage account causing 'Could not verify copy source' exception.

I am copying using uri like below...Is there something wrong am doing here? I am using Java 11

destinationBlob.startCopy(uri);

Caused by: com.microsoft.azure.storage.StorageException: Could not verify copy source.

I checked storage Blob logs around the same time when this occured I also see 404 'ResourceNotFound' for that particular file and this issue is occuring sporadically.

Can anyone assist on this issue please? @deherman-MSFT

@AsheNone Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

• Can you please check the access level , that would be causing the issue, Lear more here on access level
• Make sure that the account name/key is proper

Blob service error codes

You can refer to this article : Copy a blob with Azure Storage client libraries

The most easiest way to move /copy (upload, delete) the data in Azure Storage Account is Azcopy (Fast Data Transfer) and Azure storage explorer tool

This is really useful information!

And this issue is occuring occasionally and when this "Could not verify copy source" issue is occured I see that AuthType is set to 'Anonymous' for GetBlob operation and when this issue doesnt happen AuthType is set to "AccessKey".

May I please know why this is occuring sporadically? @Sumarigo-MSFT @deherman-MSFT
