I was talking about input validation like the middy middleware where you can check for Ajv input. So you can allow for example if the string is valid inside an array. I am curious now how you do this kind of validation with AppSync and Dynamo talking to each other without a lambda. (I never used AppSync and GraphQL)

Ah, I see. For those, you can perform validation in the VTL request template.
