load_workbook fails when loading excel file with blue style fill in cells. How do I fix the error? Click post to see error.

I wrote a python script to load an excel file with blue style fill in the excel sheet (blue color background in cells) and the load_workbook function keeps failing with the error below:

wb = load_workbook(excel file)

TypeError: expected <class 'openpyxl.styles.fills.Fill'>

How do I fix this error using python? Thank you!
