SDS - Sync & import of new data fails

Hi together,

we use School Data Sync version 2.1 with a configured flow for automatic import of the current CSV files runs normally without any visible errors, but the data from the CSV files is not imported from the local server.

I created the flow from “Automate CSV upload for task data synchronization.” In the flow, I was also able to open and select the local file system via the data gateway, so there is a connection to the server. The problem is that the files are not being imported.

Can anyone help with this error?

THX
