Like @Ecaterina Menovsky  , I too am receiving an error when running data syncs on external Snowflake Data sets. I'm receiving the same error: Something went wrong while executing the remoteSync_AttendedMinsPartsConfs node: Error copying remote csv file to local. RMT(/home/waveconn/logs/waveconnectoragent/data/ .....  AttendedMinsPartsConfs.csv: permission denied

Again, it is never the same data sets I'm syncing and I can manually sync later in the day without issues.  It is more like 50% of the overnight scheduled syncs fail and subsequent dataflows don't update.  This issue started happening on 1/14 without any changes.  The Snowflake database shows the login from Salesforce and delivers the anticipated records.  It seems to be failing when the data is returned to SF  Any thoughts?

Thanks!
