Localstack using CDKlocal sends requests to wrong url for DynamoDB

Is there an existing issue for this?

Current Behavior

I have a cdk app with api gateway, lambda and dynamodb. This is from the the course - https://frontendmasters.com/courses/go-aws/

Link to code repo - https://github.com/Melkeydev/FrontEndMasters/tree/chapter_3/cdkExample

I am using local stack and followed every instruction.

After deploying when I send the request to gateway/register I get below error for some reason cdklocak is sending request amazon's dynamoDB

{"errorMessage":"RequestError: send request failed\ncaused by: Post "https://dynamodb.ap-south-1.amazonaws.com/\": tls: failed to verify certificate: x509: certificate is valid for *.amplifyapp.localhost.localstack.cloud, *.cloudfront.localhost.localstack.cloud, *.dkr.ecr.eu-central-1.localhost.localstack.cloud, *.dkr.ecr.eu-west-1.localhost.localstack.cloud, *.dkr.ecr.us-east-1.localhost.localstack.cloud, *.dkr.ecr.us-east-2.localhost.localstack.cloud, *.dkr.ecr.us-west-1.localhost.localstack.cloud, *.dkr.ecr.us-west-2.localhost.localstack.cloud, *.elb.localhost.localstack.cloud, *.eu-central-1.opensearch.localhost.localstack.cloud, *.eu-west-1.opensearch.localhost.localstack.cloud, *.execute-api.localhost.localstack.cloud, *.lambda-url.eu-central-1.localhost.localstack.cloud, *.lambda-url.eu-west-1.localhost.localstack.cloud, *.lambda-url.us-east-1.localhost.localstack.cloud, *.lambda-url.us-east-2.localhost.localstack.cloud, *.lambda-url.us-west-1.localhost.localstack.cloud, *.lambda-url.us-west-2.localhost.localstack.cloud, *.localhost.localstack.cloud, *.opensearch.localhost.localstack.cloud, *.s3-website.localhost.localstack.cloud, *.s3.localhost.localstack.cloud, *.scm.localhost.localstack.cloud, *.snowflake.localhost.localstack.cloud, *.us-east-1.opensearch.localhost.localstack.cloud, *.us-east-2.opensearch.localhost.localstack.cloud, *.us-west-1.opensearch.localhost.localstack.cloud, *.us-west-2.opensearch.localhost.localstack.cloud, localhost.localstack.cloud, sqs.eu-central-1.localhost.localstack.cloud, sqs.eu-west-1.localhost.localstack.cloud, sqs.us-east-1.localhost.localstack.cloud, sqs.us-east-2.localhost.localstack.cloud, sqs.us-west-1.localhost.localstack.cloud, sqs.us-west-2.localhost.localstack.cloud, not dynamodb.ap-south-1.amazonaws.com","errorType":"baseError"}

Hi @Prakhar-FF13 !
Thank you for your report. This issue is already known - the transparent endpoint injection redirects requests to AWS to LocalStack - however the logic to disable certificate validation for those requests does currently not work with go lambdas.

Support for go lambdas is on our roadmap, however I am currently unable to provide an ETA for it.

Until then, please try to manually set your endpoint in your AWS SDK client creation as explained in our documentation regarding the go AWS SDK: https://docs.localstack.cloud/user-guide/integrations/sdks/go/ .

We are always trying to improve user experience and remove the need for special configuration like this, but sadly for now it is necessary when using go.
