Paste charts from Excel to Word error - The Remote Server Machine does not exist (Error 462) - vba

Question

I have a macro which carries out the following logic in VBA in excel:
Opens a word document
Loop through all the pre set bookmarks in the document
When a bookmark is found, loop through all the chart objects in a specific sheet, when the Chart Name matches the bookmark name, copy that into the word doc
I am running into Error 462 on the second run of the macro. I realise it's to do with not referencing an object properly but I cant seem to find where the culprit is.
My code looks like this:
Sub buildDocument()
'#### Initialise our variables
Dim wdApp As Word.Application
Dim wdDoc As Word.Document
Dim theWorksheet As Worksheet
Dim Chart As ChartObject
Dim wdBookmarksArray() As Variant
Dim counter1 As Integer
Dim counter2 As Integer
Dim noCharts As Integer
Dim counter4 As Integer
Dim PasteObect As Variant
Dim quarter As String
Dim sheetsArr As String
'#### Switch off update ####
Application.ScreenUpdating = False
'#### Create a new word doc; minimise; ####
Set wdApp = New Word.Application
With wdApp
.Visible = True
.WindowState = wdWindowStateMinimize
End With
On Error GoTo ErrorHandler
'#### Build a dialog box to find the
' correct word template file ####
Set wdDoc = wdApp.Documents.Open(openDialog())
counter2 = 1
counter3 = 1
For counter1 = 1 To wdDoc.Bookmarks.Count
'#### Export "New Issue Timing" graphs to
' word document ####
Call copyGraphs(newIssuesTiming, _
counter1, _
wdDoc, _
wdApp)
Next
ThisWorkbook.sheets(mainSheet).Select
Set wdApp = Nothing
Set wdDoc = Nothing
Exit Sub
ErrorExit:
wdDoc.Close
wdApp.Quit
Set wdApp = Nothing
Set wdDoc = Nothing
Exit Sub
ErrorHandler:
Dim error_report As ErrorControl
Set error_report = New ErrorControl
error_report.SetErrorDetail = Err.Description
error_report.SetErrorNumber = Err.Number
error_report.SetErrorSection = "BUILD_WORD_DOC"
If error_report.GenerateErrorReport Then
Resume ErrorExit
End If
Set error_report = Nothing
My copyGraphs looks like:
Sub copyGraphs(sheet As String, _
counter1 As Integer, _
wdDoc As Word.Document, _
wdApp As Word.Application)
Dim wdBookmarksArray() As Variant
Dim counter2 As Integer
Dim Chart As ChartObject
Dim theWorksheet As Worksheet
Dim noCharts As Integer
Dim counter4 As Integer
Dim PasteObect As Variant
Dim quarter As String
Dim sheetsArr As String
For Each Chart In ThisWorkbook.sheets(sheet).ChartObjects
If wdDoc.Bookmarks(counter1).name = Chart.name Then
ThisWorkbook.sheets(sheet).ChartObjects(Chart.name).Copy
wdApp.Selection.Goto What:=wdGoToBookmark, name:=wdDoc.Bookmarks(counter1).name
wdApp.Selection.PasteSpecial DataType:=wdPasteEnhancedMetafile
End If
Next
End Sub
The copyGraph Sub is in the same module as the sub that calls it.

Adding ByVal did in fact work, but required the excel sheet to be closed and reopened to clear all the objects from memory.

The below code works:
Sub buildDocument()
'#### Initialise our variables
Dim wdApp As Word.Application
Dim wdDoc As Word.Document
Dim theWorksheet As Worksheet
Dim Chart As ChartObject
Dim wdBookmarksArray() As Variant
Dim counter1 As Integer
Dim counter2 As Integer
Dim noCharts As Integer
Dim counter4 As Integer
Dim PasteObect As Variant
Dim quarter As String
Dim sheetsArr As String
'#### Switch off update ####
Application.ScreenUpdating = False
'#### Create a new word doc; minimise; ####
Set wdApp = New Word.Application
With wdApp
.Visible = True
.WindowState = wdWindowStateMinimize
End With
On Error GoTo ErrorHandler
'#### Build a dialog box to find the
' correct word template file ####
Set wdDoc = wdApp.Documents.Open(openDialog())
counter2 = 1
counter3 = 1
For counter1 = 1 To wdDoc.Bookmarks.Count
'#### Export "New Issue Timing" graphs to
' word document ####
Call copyGraphs(newIssuesTiming, _
counter1, _
wdDoc, _
wdApp)
Next
ThisWorkbook.sheets(mainSheet).Select
wdDoc.Save
wdDoc.Close
wdApp.Quit
Set wdApp = Nothing
Set wdDoc = Nothing
Exit Sub
ErrorExit:
wdDoc.Close
wdApp.Quit
Set wdApp = Nothing
Set wdDoc = Nothing
Exit Sub
ErrorHandler:
Dim error_report As ErrorControl
Set error_report = New ErrorControl
error_report.SetErrorDetail = Err.Description
error_report.SetErrorNumber = Err.Number
error_report.SetErrorSection = "BUILD_WORD_DOC"
If error_report.GenerateErrorReport Then
Resume ErrorExit
End If
Set error_report = Nothing
End Sub
Routine to copy graphs :
Sub copyGraphs(ByVal sheet As String, _
ByVal counter1 As Integer, _
ByVal wdDoc As Word.Document, _
ByVal wdApp As Word.Application)
Dim wdBookmarksArray() As Variant
Dim counter2 As Integer
Dim Chart As ChartObject
Dim theWorksheet As Worksheet
Dim noCharts As Integer
Dim counter4 As Integer
Dim PasteObect As Variant
Dim quarter As String
Dim sheetsArr As String
For Each Chart In ThisWorkbook.sheets(sheet).ChartObjects
If wdDoc.Bookmarks(counter1).name = Chart.name Then
ThisWorkbook.sheets(sheet).ChartObjects(Chart.name).Copy
ThisWorkbook.sheets(sheet).ChartObjects(Chart.name).Copy
wdApp.Selection.Goto What:=wdGoToBookmark, name:=wdDoc.Bookmarks(counter1).name
wdApp.Selection.PasteSpecial DataType:=wdPasteEnhancedMetafile
End If
Next
End Sub
