[x] bug report [ ] feature request

Detailed description

Possibly related/duplicate of https://github.com/localstack/localstack/issues/3175 When using java client with anonymous credentials putting a new object with a slash in the key. For example:

client.putObject("testbucket", "file", "content"); // Works
client.putObject("testbucket", "subdir/file", "content"); // Fails

When faking the credentials it works (tested on 0.12.2 and 0.12.4)

Expected behavior

S3 operations work.

Actual behavior

This is a regression since version 0.10.5
The log in the container is: 2021-01-10T08:51:25:INFO:localstack.services.edge: Unable to find forwarding rule for host "localhost:4566", path "/", target header "", auth header "", data "b''"

Steps to reproduce

Command used to start LocalStack

A snippet from docker-compose:

  localstack-v2:
    container_name: localstack-v2
    image: localstack/localstack:0.12.2
    ports:
      - "4566:4566" # edge service
      - "${PORT_WEB_UI-8091}:${PORT_WEB_UI-8080}"
    environment:
      - SERVICES=s3,lambda,dynamodb,sqs
      - LAMBDA_DOCKER_NETWORK=dockerized_localenv_localenv
      - DEBUG=1
      - PORT_WEB_UI=8081
      - DATA_DIR=/tmp/localstack/data
      - DOCKER_HOST=unix:///var/run/docker.sock
    volumes:
      - ${NON_VERSIONED_FILES_BASE}/localstack-v2:/tmp/localstack
      - /var/run/docker.sock:/var/run/docker.sock
    networks:
      - localenv
