Recently i have upgraded Katalon_Studio to version 7.2.1.
I have faced the same issue as mentioned in above story for my excel writing. I have created the custom keyword file with the content in ExcelKeywords.groovy from (https://github.com/katalon-studio/katalon-excel-keyword/blob/master/ExcelKeywords/Keywords/com/kms/katalon/keyword/excel/ExcelKeywords.groovy) after custom file adding i am able to run my excel writing test cases but every time Whenever i am running the test i am getting custom file error. I can guess something going wrong in my custom keyword, but unable to spot the same.
Could anyone please help me to ignore or overcome the same ?
