If you only have one or two GDS files, you can manually import, and you can check if the import contains no error. You can also use script to import one by one. Please refer the sample here https://support.lumerical.com/hc/en-us/articles/360034901933-Importing-and-exporting-GDSII-files

When you get that error message, it indicates that the gds file contains some kind of error, or Lumerical tool cannot recognize it. Please check its creation and make sure it obeys the Lumerical rules.
