Error on Choice Stage, cannot compare unknown

[RicardoCabrera]

Hello I have a temporary collection that gets populated when the bot runs, it then goes to a choice stage and it follows the path depending on the values from that temporary collection, I don't want to predefine the fields on that temp collection as the users can add more columns to the source file at any given point in time, would you recomend using a decision stage instead of a choice stage, or any other suggestions? thanks in advance

If the users can add more columns but you do not intend to use the extra columns, I would say you should have 2 collections. Collection 1 would be undefined and takes whatever columns are received from the source file. Then take only the data out that you need by specifically referencing the column names and placing the data into your Collection 2, which has predefined columns.
