    You either need to create a DyanmoDB VPC Endpoint in the VPC, or add a NAT Gateway to the VPC, and only deploy the Lambda function in subnets that have a route to the NAT Gateway.

    Depending on the VPC configuration subnet/Security Group of your lambda,

    If your lambda is in a private subnet :

    • If you want a secure internal way, you can pass with VPC endpoint
    • Else if you want to pass with internet, you must have a NAT Gateway.

    Check also the security groups/NACLS….
