Error saving after using Add-Worksheet with this specific file

[mavhc]

scienceTemplate.xlsx
test.xlsx
Version 7.8.6

Using the 2 files attached, the follow code gives an error

$template = Open-ExcelPackage "scienceTemplate.xlsx"
$wsScience = $template.Workbook.Worksheets["Science"]

$destination = "test.xlsx"

$excel = Open-ExcelPackage $destination

$ws = Add-Worksheet -ExcelPackage $excel -WorkSheetname "Science" -ClearSheet -CopySource $wsScience

Close-ExcelPackage $excel

Results in:

At C:\Program Files\WindowsPowerShell\Modules\ImportExcel\7.8.6\Public\Close-ExcelPackage.ps1:29 char:20
+             else { $ExcelPackage.Save() }

Using a simpler template file works fine, tried to find a minimal case, and ended up deleting everything, so possibly something about the formatting is the problem?

So this works. I'm wondering if the issue is that the science sheet you have has formatting in it.

$xlSrc = "$PSScriptRoot\ImportExcelExample.xlsx"
$xlDst = "$PSScriptRoot\myTest.xlsx"

Remove-Item $xlSrc -ErrorAction Ignore
Remove-Item $xlDst -ErrorAction Ignore

1..10 | Export-Excel $xlSrc 

$src = Open-ExcelPackage $xlSrc
$dst = Open-ExcelPackage $xlDst -Create

$null = Add-Worksheet -ExcelPackage $dst -WorksheetName Test -CopySource $src.Sheet1 -ClearSheet

Close-ExcelPackage $src
Close-ExcelPackage $dst -Show
