Hi @jaymeen-unadkat-differenz, can you provide us with the schema that you used, redacted if needed. Alternatively, you can run

amplify diagnose --send-report

to create a zip of the amplify project which includes the schema. (https://docs.amplify.aws/swift/tools/cli/reference/diagnose/)

Can you also provide us with the code snippet that you are using to perform the save?

Usually createAt and updatedAt are system-level fields on the model, so if you had overridden them in the schema and marked them as required, that may be related to the error you're seeing. We won't know until we have your schema to analyze and reproduce the problem.

This is the schema which we are using

type Imbybe @model @auth(rules: [{allow: public}]){
  pk: String! @primaryKey(sortKeyFields: ["sk"])
  sk: String!
  gsi1: String @index(sortKeyFields: ["gsisk1"])
  gsisk1: String
  name: String

Thanks for the schema, any code snippets and logs leading up to that error?
