I am using Python 2.7 and ArcGIS 10.4.1 to create a script that walks through folders and scans for mxds. I use a set to get unique data sources and copy the data to a new folder keeping the same data format. I would then like to access the map document and repath all layers and tables to the copied data. I'm struggling to get the tables repathing code to work. In the below example, I have a fGDB table in the mxd and have copied the fGDB that it sits in to a new folder. I would thus like to repath to the table in the copied fGDB.

```
import arcpy, os
mxdrep = arcpy.mapping.MapDocument("CURRENT")
dfsrep = arcpy.mapping.ListDataFrames(mxdrep)

ignoreStringList = ["Vendor", "vendor", ".sde"]
#Target folder containing the copied fGDB
dbFolder = os.path.join(projFolderPath, "Databases")
for dfrep in dfsrep:
   tablesRep = arcpy.mapping.ListTableViews(mxdrep, "", dfrep)
   tabRepDataSrc = tableRep.dataSource
   #Excludes data sources containing list of sub strings
   if not any(folders in tabRepDataSrc for folders in ignoreStringList):
      #Create the table view for each table
      tableRepView = arcpy.mapping.TableView(tabRepDataSrc)
      # Get the directory level to replace
      tabPath = os.path.dirname(tabRepDataSrc)
      tabRepPath = os.path.dirname(tabPath)
      #Repath the tables
      tableRepView.findAndReplaceWorkspacePath(tabRepPath, dbFolder)

```

This gives a rather cryptic error;

```
Runtime error
