Hi @Anonymous ,

>> i have a dataset with source as  csv file from network drive.  It was working fine. but since yesterday i got error.

Which datasource type the "network drive" as you said is referred to ,OneDrive for Business or others?

Please check if the path of your csv file is changed.

If your dataset contains not only the csv files form network drive but also the on premise data source, and have installed the gateway, try to upgrade the gateway to the latest version.

Could you please show us the issue page in screenshot for further analysis?

@v-xicai    it is not one drive file....the file is stored in shared network drive..when trying to add datasource to gateway
