Running a Cloudformation project on localhost with DynamoDB, Lambda, and API Gateway resources using Localstack - aws-lambda

Question

I have a CloudFormation project with the following configs.
AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: >
team-up-interactions
Resources:
handler:
Type: AWS::Serverless::Function
Properties:
Description: Team Up interaction handler logic
CodeUri: ./handler/
Handler: handler.handler
Runtime: nodejs14.x
EventInvokeConfig:
MaximumRetryAttempts: 0
Timeout: 60
Environment:
Variables:
dbStorage: !Ref dbStorage
dbSearch: !Ref dbSearch
Architectures:
- x86_64
Policies:
- AWSLambdaBasicExecutionRole
Events:
HttpPost:
Type: Api
Properties:
Path: '/interaction-endpoint'
Method: post
dbStorage:
Type: AWS::DynamoDB::Table
Properties:
AttributeDefinitions:
-
AttributeName: "id"
AttributeType: "S"
KeySchema:
-
AttributeName: "id"
KeyType: "HASH"
BillingMode: "PAY_PER_REQUEST"
dbSearch:
Type: AWS::OpenSearchService::Domain
Properties:
EngineVersion: 'OpenSearch_1.1'
ClusterConfig:
InstanceCount: '1'
InstanceType: 't3.small.search'
EBSOptions:
EBSEnabled: true
VolumeSize: '20'
VolumeType: 'gp2'
These configs should create a Lambda, a DynamoDB table, and an OpenSearch Domain.
I am using LocalStack's samlocal command to run the project.
samlocal local start-api --host 0.0.0.0 --warm-containers EAGER
I have the following code that attempts to connect to the DynamoDB and is failing.
try {
const client = new DynamoDBClient({
endpoint: "http://localhost:4566"
});
await client.send(new UpdateItemCommand({
TableName: process.env.dbStorage,
Key: marshall({id: "test"}),
ExpressionAttributeValues: marshall({":test": "hello world"}),
UpdateExpression: "SET test = :test",
}));
//
const x = await client.send(new GetItemCommand({
TableName: process.env.dbStorage,
Key: marshall({id: "test"}),
}))
console.log("JSON.stringify(x)");
console.log(JSON.stringify(x));
} catch (ex) {
console.log("JSON.stringify(ex)")
console.log(JSON.stringify(ex))
}
This is the error.
{
"errno": -111,
"code": "ECONNREFUSED",
"syscall": "connect",
"address": "127.0.0.1",
"port": 4566,
"$metadata": {
"attempts": 1,
"totalRetryDelay": 0
}
}
I also tried creating the client without any parameter and that failed too.
const client = new DynamoDBClient();
This is the error.
{
"name": "UnrecognizedClientException",
"$fault": "client",
"$metadata": {
"httpStatusCode": 400,
"requestId": "VAHE0KG1D1UTE9AQNAREF9RJHFVV4KQNSO5AEMVJF66Q9ASUAAJG",
"attempts": 1,
"totalRetryDelay": 0
},
"__type": "com.amazon.coral.service#UnrecognizedClientException",
"message": "The security token included in the request is invalid."
}
How can I get LocalStack to create the DynamoDB resource from the configurations and/or how do I access those resources?
Update
I am using this endpoint and it seems to be able to connect the client to localstack.
const client = new DynamoDBClient({
endpoint: "http://host.docker.internal:4566",
});
I get the following error when doing a GetItemCommand
ResourceNotFoundException: Cannot do operations on a non-existent table
