go mod init lambda-dynamodb
go get github.com/99designs/gqlgen
go run github.com/99designs/gqlgen init
go run github.com/99designs/gqlgen generate
go get github.com/aws/aws-sdk-go-v2
go get github.com/aws/aws-sdk-go-v2/config
go get github.com/aws/aws-sdk-go-v2/service/dynamodb

権限

IAMロールを作成して、アクセスキーを環境変数へ
今回は簡単のためAmazonDynamoDBFullAccessとAWSLambda_FullAccessを付与。
