Access Denied of 4 lists of the 46 lists exported to csv-file

I have 46 lists, and I have a code that I execute 46 times which exports a list to csv-file. All 46 lists will be exported to a csv-file accept 4 lists. The error of the 4 lists are; Access denied. Why 42 lists will export to csv-file successfully and 4 not, I do not understand. anyone?

This is the code:

$  hashTable = @() $  items = Get-PnpListItem -List "My schedule" #klaar foreach($  item in $  items) { $  HashTable += New-Object psobject -Property @{  'Datum'=$  item.FieldValues.Datum.ToLocalTime().ToString("dd.MM.yyyy"); '00:00 - 07:59'=$  item.FieldValues._x0030_0_x003a_00_x0020__x002d__; '08:00 - 16:59'=$  item.FieldValues._x0030_8_x003a_00_x0020__x002d__; '17:00 - 23:59'=$  item.FieldValues._x0031_7_x003a_00_x0020__x002d__;   'Opmerkingen'=$  item.FieldValues.Opmerkingen;    }  }  $  hashTable | Select Datum,'00:00 - 07:59','08:00 - 16:59','17:00 - 23:59',Opmerkingen |  epcsv "My schedule" -NoT
