cannot copy private incremental disk snapshot to storage account

[GauravChawda]

Which version of the AzCopy was used?

10.23.0

Which platform are you using? (ex: Windows, Mac, Linux)

Linux (6.2.0-1019-azure)

What command did you run?

azcopy copy https://md-impexp-tfwkrt1snkcg.z44.blob.storage.azure.net/gt13wmp4rwqg/relaycor?si=8454a9c86e434c7f943cae52154651f10a20d4b6fa314e2f96865e5e6f4a862e&sig=-REDACTED-&sr=b&sv=2018-03-28 https://tempstorageaccountxx.blob.core.windows.net/snaps/new_page_blob?se=2024-02-14t14%3A18%3A49z&sig=-REDACTED-&sp=rwdlacupiytfx&spr=https&srt=sco&ss=bfqt&st=2024-02-14t06%3A18%3A49z&sv=2022-11-02

What problem was encountered?

2024/02/14 06:21:07 ERR: [P#0-T#0] COPYFAILED: https://md-impexp-tfwkrt1snkcg.z44.blob.storage.azure.net/gt13wmp4rwqg/relaycor : 409 : 409 Source blob of a copy operation cannot be non-snapshot incremental copy blob.. When Uploading page from URL. X-Ms-Request-Id: 6e5fb3ed-901e-003f-160d-5fa5e7000000

How can we reproduce the problem in the simplest way?

1. create incremental disk snapshot with networking option AllowPrivate
2. generate SAS for that snapshot
3. generate SAS for the destination storage account
4. use azcopy copy "<snapshot_sas>" "<storage_account_sas>"

Have you found a mitigation/solution?

No

Additional Context

I ensured that the vm which has been used for azcopy has access to that private snapshot (wget successfully downloads the snapshot VHD in VM).
The same azcopy copy command is working fine with networking option AllowPublic, but due to security reasons we can't make snapshot public.

If you can point me to the right directions, I am more than happy to contribute to azcopy.
