Hello @asnth
There could be several reasons why you are unable to preview or copy the data, such as the size of the list, the column types, or the query you are using.
To troubleshoot this issue, I recommend the following steps:
- Check the size of the list: If the list is very large, it may take a long time to preview or copy the data. You can try to limit the number of records returned by using the Query option to filter by modified date or select the Id column alone.
- Check the column types: If the list contains columns with complex data types, such as lookup columns or managed metadata columns, it may cause issues with the data preview or copy operation. You can try to exclude these columns from the copy operation or use a different data type mapping.
- Check the Request timeout: If the data preview times out after a minute or so, it may be due to the Request timeout setting. You can try to increase the Request timeout to a higher value, such as 2 hours, to see if it resolves the issue.
- Check the network connectivity: If the issue persists, it may be due to network connectivity issues between Azure Data Factory and SharePoint Online. You can try to test the network connectivity by using a different tool, such as PowerShell or SharePoint Online Management Shell, to see if you can access the list data. If none of these steps resolve the issue, you may need to contact Microsoft Support for further assistance. I hope this helps! Let me know if you have any other questions.
