GItlab Web API fuzzer

Hi GitLab community.
I am currently working on the GitLab Web API fuzzer and I am trying to test my web api with it.
However I am not entirely sure how to set it up.
Currently my gitlab ci looks like this:

include:
    - template: API-Fuzzing.gitlab-ci.yml

stages:
    - build
    - fuzz
            
variables:
    #
    # --] Required Configuration ------------------------------------
    #
    # Test using an OpenAPI file
    FUZZAPI_OPENAPI: openapi.json
    #
    # Provide the base url for the target.
    # This will override the base URL in the OpenAPI specification
    FUZZAPI_TARGET_URL: http://target:80
    #
    # --] Optional configuration [------------------------------------
    #
    # FUZZAPIOVERRIDESJSON is set in the CI/CD Variables section of Settings
    FUZZAPI_OVERRIDES_ENV: $FUZZAPIOVERRIDESJSON
    #
    # Docker image published here
    OPENAPI_TARGET_IMAGE: registry.gitlab.com/web-fuzzers-thesis-project/dvws-node-fuzz-testing:latest

build:
    stage: build
    image: docker:19.03
    services:
        - docker:19.03-dind
    script:
        #
        # Build target container
        - docker build -t $OPENAPI_TARGET_IMAGE .
        #
        # Push to registry
        - docker login -u gitlab-ci-token -p $CI_JOB_TOKEN $CI_REGISTRY
        - docker push $OPENAPI_TARGET_IMAGE
    artifacts:
        paths:
            - $FUZZAPI_CONFIG

apifuzzer_fuzz:
    script:
        - echo "fuzzer running"
    services:
        - name: $OPENAPI_TARGET_IMAGE
          alias: target

# end

This template is the one that I have copied from the example OpenAPI project given by GitLab in: Web API fuzzer (OpenAPI example).
I have modified so that it would work with my web api, however, every time I run it I get the following error: start service container: Error response from daemon: Cannot link to a non running container

I am new to setting up Gitlab CI/CD and I was wondering if it is possible to run a web api locally in gitlab with docker and then use the docker image to send requests to that web api.
