Errors loading flow variables into node : String for key "0" not found

hi, could you please explain what could caused “Errors loading flow variables into node : String for key “0” not found”. I have a few columns, lets say, with year number 2022, 2023, 2024, then a few variables year0=2022, year1=2023, year2=2024, I would like to filter column with name “2022”, I use a variable year0 and get this error. I use knime 4.5.1.

My guess is that you’re using an integer flow variable when the node is asking for and expecting a string flow variable.
