Filter Wizard returning unknown error

UIPath throws me the following error:

Can anyone help me identify what I’m doing wrong?

Can you show me the column of dtFirstVersion

I mean to keep only certain columns (containing critical information i can’t show - not x1, x2, x3…) The x1, x2, x3 is supposed to represent column headers/names. UIPath reads an excel file and posts it into the dtFirstVersion variable (I think), it does this correctly as there’s no error with the dtFirstVersion

You should double check column names.
E.g. Why some are black and some brown in 2nd screen? Why there is the leading space?


worked around it with excel vba as uipath didnt work
