Error while copying, "An error with the same key has been already added".


  • I want to copy all the files of blob folder to sql dw table. when I debug the pipeline, I got a an error "An error with the same key has already been added". I have checked the pipeline for the issues but it doesn't contain any duplicate values in my code.

  • Hello , 

    We did checked the copy activity from a blob container( with two delimited files )  to SQLDWH and it did worked without issues .

    At this time we are not sure if any of other properties are not properly set and so you are running into this .

    As you can see that the failure is immediate as duration is 00:00:00 ( in the screenshot) , I think its not coming from the source side , but to some configuration issue .


    Thanks Himanshu
