Dataflow create linked entity with gateway error "Unexpected Error"

Hi mpi_gov_vn ,

According to your description, your data source comes from local or cloud. Web. Content does not require a gateway to connect.
You can enter the credentials set in the activation "management gateway": allow the user's cloud data source to be refreshed through this gateway group. These cloud data sources do not need to be configured under this gateway group.

Or you can check the simliar solution case:

If the problem is still not resolved, please provide detailed error information and let me know immediately. Looking forward to your reply.

Best Regards,
Henry
