Hi,
I am not able to load the workbook using latest openpyxl \(3.0.3\), getting the keyerror \(please see attached image\). I can get the workbook to load with openpyxl version 2.4.0, However when I upgrade to version 3.0.3 it starts throwing the error. I have attached the sample Excel file to this issue. There is only one image in the file, however loading image is throwing the error.
Thanks,
Pratyuma
