What does "unexpected response code for operation : 1" mean?

Question

Am getting "unexpected response code for operation : 1" from an app trying to insert records in an Azure table storage.

Am basically placing the data in a TableOperation and already batching the inserts by 100 row chunks.

Can't really find much on the web about the specific "1" code in this Azure error message.

Answer 1

When the batch operation fails, table service returns HTTP status code 400 and along with that it sends the index of the entity which caused this batch to fail.

"unexpected response code for operation : 1"

This means there's an error while inserting entity at position 1 in your batch.
