SOLVED Datasource error: could not find file

[DerWunderman]

Hi there!

I'm trying to refresh a datasource connected to a local text file. Unfortunately I'm getting “Could not find file" error.

I’m sure that file exists and all necessary permissions are granted.

Gateway connection test proves that:

Would you mind advising me how can I resolve the issue?

Solved! In a case of a file source a gateway does not use credentials specified on datasource settings page, but uses its service credential! It’s necessary to grant  permissions exactly for service account on a file itself!
