Question

I am trying to import excel module in PS 7.1.0 but am getting the following error:

MethodInvocationException: C:\Temp\Deploy-iDMZ\Modules\ImportExcel\7.1.1\Public\Export-Excel.ps1:672 Line | 672 | else { $pkg.Save() } | ~~~~~~~~~~~ | Exception calling "Save" with "0" argument(s): "Error saving file | C:\Temp\Deploy-iDMZ\iDMZ-Parameters-XYZ1234.xlsx"

This is my code:
