            Serverless Offline & DynamoDB throws Local UnknownEndpoint: Inaccessible host: localhost at port 8000 Service may not be available in localhost region
            Asked 2022-Apr-11 at 10:19

            I'm playin around with Serverless and I have no luck getting serverless-offline to work with serverless-dynamodb-local. I have very minimal setup, it takes 3minutes to reproduce, I did it like this:

            1. Generate a TS Serverless project like - sls create -t aws-nodejs-typescript --path folder-name
            2. install dependencies npm i
            3. Add DynamoDB local npm install --save serverless-dynamodb-local
            4. Add serverless offline npm install serverless-offline --save-dev
            5. Install dynamodb sls dynamodb install

            Now I update serverless.ts file like

            Turns out it's most likely an environment issue of my MacBook. My friend tried exactly the same code on his computer and it was working for him.

            Still if anyone has an idea why this might be happening let me know please.

            EDIT: So turned out it was a problem with my node version, I was running v17.3.1. After switching to v16.4.0 it works like a charm. 🥳

            NestJS - GraphQL not working in my jest E2E "is not a function"
            Asked 2022-Feb-20 at 14:45

            It's 3 days i am on this problem of E2E tests on my GraphQL application with NestJS + Apollo / Express.

            When I am running my app with serverless offline or directly with my main file, it's working perfectly. I have my graph and all things I need :)

            But, when I am running E2E tests with Jest, I received an error from the await app.init() inside the beforeEach.

            After playing with the package.json and dependencies, the error throwed is TypeError: (0 , schema_1.makeExecutableSchema) is not a function.

            Someone have any idea please ? I am totally blocked ... :(

            After many hours of intense programming ... I finally found the problem.

            Be careful if you use some "alias" for imports, because it can overwrite some of the packages used.

            Here, i use the @graphql alias, and it breaks all my tests. When I remove it, the problem disappear.

            Your lambda function don't have the panda module installed

            You need to use the serverless-python-requirements plugin : To use it you need docker on your machine and to create a requirement.txt file in your service with the packages you need in your lambda

            I use nodejs s3 package "aws-sdk" It works fine when I use serverless-offline run on my mac. The s3.getSignedUrl and s3.listObjects function both work fine.

            But when I run my deployed app, the s3.getSignedUrl works fine but the s3.listObjects not. I got this error in CloudWatch:

            In CloudWatch > Log groups > /aws/lambda/mamahealth-api-stage-userFilesIndex:



            Answered 2021-Dec-27 at 10:54

            In the last line of your IAM role, you grant permissions the lambda function to perform s3:PutObject, s3:GetObject, s3:DeleteObject and s3:ListBucket on the S3MasterResourceBucketArn/*.

            I believe that the first 3 actions and the last one have different resource requirements. For the first 3 (PutObject, GetObject, and DeleteObject) the resource name is correct. For the last one (ListBucket) I believe it must be the arn of the bucket without the star at the end (``S3MasterResourceBucketArn`).

            As a good practice, you should split your policy into multiple statements, like:



            AWS Lambda Deployment - AccessDeniedException

            Answered 2021-Dec-20 at 06:48

            The role assumed by your lambda function does not have required permissions to access the Dynamo Db table. To solve this, you need to attach the appropriate policy to your lambda function role.

            This page contains a policy that grants Read/Write access to your lambda function.

            Asked 2021-Dec-15 at 18:03

            In my sls project, I setup sqs offline usage as shown below using this article.

            1. npm installed serverless-offline-sqs as dev dependency
            2. Included serverless-offline-sqs after serverless-offline in serverless.ts plugins section
            3. Added custom configuration for the Queue,


            Answered 2021-Dec-15 at 18:03

            Figured it out. Nothing wrong with plugin. Though I added lambda function handler for SQS events, I forgot to include the function in serverless.ts under "functions" resource. Including it in functions autoCreated the queue as expected.

            Answered 2021-Dec-15 at 16:51

            After some research we were able to connect our lambda to our vpc using serverless. The solution was: Stop using serverless-vpc-plugin.

            It turns out that serverless-vpc-plugin, automatically creates a AWS VPC, which is not what we were looking for. We already had our VPC created using terraform.

            From serverless-vpc-plugin documentation

            Automatically creates an AWS Virtual Private Cloud (VPC) using all available Availability Zones (AZ) in a region.

            In other words, serverless-vpc-plugin doesn't make sense when the target vpc already exists
