Successful mongoimport after logged error

From command line, (administrator level or not) and also from powershell (elevated and standard) my mongoimport is successful, but throws this error first (then continues and works correctly). I’d like to modify the script to avoid the error, but can’t find anything about this in the docs Any ideas? Thanks

PS C:\Program Files\MongoDB\Tools\100\bin>  .\mongoimport mongodb:// --db='WW' --collection='TimeStamp' --type csv  --file='C:\XXSystems\TimeStamp.csv' --drop --columnsHaveTypes --fieldFile='C:\XXSystems\TimeStampFields.txt'
