include remote and include local on the same file are having different results

Hi While I'm using include on the same .yml file which is present locally vs in a remote repo I see different behaviors. When I use the local one, everything works fine. But when I use the remote one I get an error that the yml is invalid. What am I missing? Thanks

Here is my gitlab-ci yml:

include: 'gitlab_common.yml'

image: maven:3-jdk-11-slim

variables:
  K8S_NAMESPACE: abc

stages:
  - build
  - quality
  - dockerize
  - test-deploy

package:
  stage: build
  script:
    - build
  artifacts:
    paths:
      - app/target/

sonar:
  stage: quality
  except:
    - master
    - dev
  script:
    - sonarqube
  dependencies:
    - package
  when: on_success
  artifacts:
    paths:
      - app/target/

dependency_check:
  stage: quality
  except:
    - master
    - dev
  script:
    - dependency_check
  dependencies:
    - package
  when: on_success
  artifacts:
    paths:
      - app/target/

update_check:
  stage: quality
  except:
    - master
    - dev
  script:
    - update_check
  dependencies:
    - package
  when: on_success
  artifacts:
    paths:
      - app/target/

dockerize:
  stage: dockerize
  image: docker:stable
  services:
    - docker:dind
  script:
    - dockerize
  dependencies:
    - sonar
  when: on_success
  tags:
    - docker
  artifacts:
    paths:
      - app/target/

test-deploy:
  stage: test-deploy
  image: "gitlab-registry.nordstrom.com/sm/docker-mvn-nonroot:3-jdk-11-slim"
  environment:
    name: test
  variables:
    K8S_TOKEN: $K8S_BEARER_TOKEN_NP_1
    K8S_CLUSTER: aws-nonprod-cluster-1
    KUBECONFIG: /tmp/kubeconfig.yml
  script:
    - deploy_k8s
    - oop_it
  dependencies:
    - dockerize
  when: on_success

And my gitlab_common.yml is: (I've truncated it for brevity)

.gitlab_common: &gitlab_common |
  [[ "$TRACE" ]] && set -eu

  function build(){
     mvn --version
     mvn -B package
  }
before_script:
  - *gitlab_common

When I try to use include: 'https:\\...\gitlab_common.yml' I get the error.
