'Cognito passwordless solution sends code multiple times
I have successfully implemented these instructions from AWS (https://aws.amazon.com/de/blogs/mobile/implementing-passwordless-email-authentication-with-amazon-cognito/), but as soon as I execute the signIn function via aws-amplify, it often takes up to 7 seconds and I receive 3 emails with different codes.
The reason for this is that the event createAuthChallenge executes the respective lambda function 3 times, which generates and sends the respective code. This only happens if I do not login/register for a certain time (~10 minutes). I thought that this might be because the function is cold and tried to keep it warm by setting "Provisioned Concurrency" in the lambda functions
- CreateAuthChallenge
- VerifyAuthChallenge
- DefineAuthChallenge
- PreSignup
- PostAuthentication
to 1 and additionally(!) tried to warm up the functions by executing them every 5 minutes via cloudwatch. I don't know what else I should do.
Thx!
