Error with Send email action in automation

[CHRISTOPHE_CHAN]

Hi guys,

I'm trying interacting with forms in emails. I'm testing a basic automation using a Created row trigger and an email action. The bot is not delivering the email as expected. The monitoring shows an error I do not understand :

Error encountered in step with name [Envoi mail]: The given key 'Yellow' was not present in the dictionary.

Any ideas ?

Thanks 

Chris

Perhaps your Automation is trying to set an Enum or EnumList a value the column doesn't allow?
