What problem was encountered?

Duplicate property odata.etag found in serialized json response after querying on RowKey. This leads to a System.Private.CoreLib: Exception while executing function: (...). System.Private.CoreLib: An item with the same key has already been added. Key: odata.etag. in Azure.Data.Tables v12.5.0.

Have you found a mitigation/solution?

No

Workaround is to touch/update the copied rows in local storage because it "resets" the etag value to a non duplicate. But this works only via storage explorer.

[Zhaph]

Also happens if you "copy table" from one account and then "paste table" into the Azurite hosted instance.

[gluwer]

I have encountered similar issue with new @azure/data-tables library for node. This new library returns etag as a part of entity like any other property but then by default it is also send in updates. Old emulator or production service just ignores etag property, but Azurite seems to save it. In subsequent updates you start to get 409 if you set etags to match.
To get it working properly you have to remove etag from entity but it is not required on production servers.

This is really the same issue, as i think Azure Storage Explorer uses new @azure/data-tables nodejs library under the hood.

Work around that worked for me: Use export to file and then import into the new table instead of using clone or copy/paste in Storage Explorer
