copy data from MongoDB to blob (json file)

Question

Hi,

I'm trying to copy data from MongoDB to Azure blob

the process failed and I'm getting this error:

The failure happened on the 'Source' side. ErrorCode=MongoDbOperationFailed,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=>Failed to operate data via MongoDB client.,Source=Microsoft.DataTransfer.Runtime.MongoDbAtlasConnector,''Type=System.InvalidOperationException,Message=Duplicate element name 'score'.,Source=MongoDB.Bson,'

can it be resolved on the Azure side?

I don't see any Duplicate elements on the MongoDB collection

Hi Reut Cohen,

Thank you for posting query in Microsoft Q&A Platform.

From the error message it seems problem is in source only. Kindly recheck if any duplicate element name called score in your mangoDb database.

However, in copy activity, under mappings tab see if any duplicate mapping happened and if yes, clear it and see if that helps.

Please let me know how it goes. Thank you.
