我无法使用谷歌应用脚本隐藏谷歌表格的最后一列

Question

so I have this sheet that I need to modify using a script as I am producing a large number of sheets and can't do everyone manually:

now this is the code that I am using that is supposed to hide the last column "AA" from the sheet beside some other things:

every line is working as expected except the line where I try to hide column AA is producing this error and I've already tried a lot of variations to this line all resulting to this error: "Exception: Those columns are out of bounds." so any help would be appreciated, thank you.

Answer 1

as specified by https://stackoverflow.com/users/14265469/yuri-khristich , using SpreadsheetApp.flush() before attempting to hide the last column in the sheet worked.
