Aws localstack get dynamo DB from lambda in localstack

Ive a lambda and a dynaoDB set in a localstack. The dyanmodDB table is correctly created(visible in web localstack + awslocal dynamodb list-tables in localstack-main container bash)

In localstack-main ( in eu-west-3)

{
    "TableNames": [
        "leads",
        "dealers"
    ]
}

In my lambda i try to :

import os,boto3
url = os.getenv("LOCALSTACK_HOSTNAME") #=some ip
port = os.getenv("EDGE_PORT") #verified = 4566
localstack_endpoint =f"http://{url}:{port}"

dynamodb = boto3.resource("dynamodb", region_name="eu-west-3",endpoint_url=localstack_endpoint)
table = dynamodb.Table("dealers")

I get a Cannot do operations on a non-existent table. I gt the same thing by replacing url by localhost.localstack.cloud.Replacing with localhost i just get no connection

dynamodb = boto3.resource("dynamodb", region_name="eu-west-3", endpoint_url=localstack_endpoint)
tables = list(dynamodb.tables.all())  
print(tables)

\>>>[ ]

Here's my docker-compose

version: "3.8"

services:
  localstack:
    container_name: "${LOCALSTACK_DOCKER_NAME:-localstack-main}"
    image: localstack/localstack:4.0.3
    ports:
      - "4566:4566"              # LocalStack Gateway
      - "4510-4559:4510-4559"    # external services port range
    environment:
      # LocalStack configuration: https://docs.localstack.cloud/references/configuration/
      - DEBUG=${DEBUG:-0}
      - AWS_DEFAULT_REGION=eu-west-3
    volumes:
      - "${LOCALSTACK_VOLUME_DIR:-./volume}:/var/lib/localstack"
      - "/var/run/docker.sock:/var/run/docker.sock"

I want to get access to the dynamoDB from the lambda in localstack
