Hi @sdrakedrake ,
I tested from my side and even when I use the sheet with id like :1234654643.21 , flow can run successfully

So I think this issue could be related to the data inside your sheet. As mentioned in this error message, is the "width" actually one of the columns from your sheet? If yes, could you please provide a sample record, maybe the first record inside your sheet? I would suppose there is conflict between the flow API and your data source.
Best Regards,
