your mapping doesn’t contain `entity` that would tell the form which entity it should use to fill the slot

`from_text` should be working without additional info

whitespace tokenizer is built inside rasa

@Ghostvv owwwww okay thanks for making it clear for me… here if **Data cleaning** is the process of fixing or removing incorrect, corrupted, incorrectly formatted, duplicate, or incomplete **data** within a dataset. then does that require some algorithm to do it or it is something that can be done manually just by looking at it??
