Hi,
My data flow failed to refresh and the error info as below.
Error: AzureBlobs ??????????????????:?€????????????????: ???????????????????€??€??€? Request ID: 724af724-f41c-c679-8c01-33a99714f226 Activity ID: f5e757ef-27e4-403d-8b7e-16cd726ca520
Please help, thanks a lot.
I don't know why it throws such unreadable information.
Which data source do you connect to?
If it used gateway, does the gateway online and connect to the data source successfully?
Best Regards
Maggie
