ADF copy data issue with RESt

Question

Hi,

I am pulling api data. I have a copy activity with the source as REST and sink as csv. The link service test for the REST is successful. But during the activity an error throws up

""Code": 11564,
"Message": "Failure happened on 'Source' side. ErrorCode=UserErrorFailToReadFromRestResource,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=An error occurred while sending the request.,Source=Microsoft.DataTransfer.ClientLibrary,''Type=System.Net.Http.HttpRequestException,Message=An error occurred while sending the request.,Source=mscorlib,''Type=System.Net.WebException,Message=The underlying connection was closed: An unexpected error occurred on a send.,Source=System,''Type=System.IO.IOException,Message=Authentication failed because the remote party has closed the transport stream.,Source=System,'"

I have tested this API with postman and curl and it works all fine.

Hi @Ram Raju ,

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

From the error message it looks like Authentication issue.

• Are you using correct request method and authentication types? Could you please review once?
• Could you please check Preview data option under source tab of Copy activity after selection REST dataset?
• Could you please share your configurations of copy activity and datasets and linked services? That may help to repro scenario.
