CircleCI throwing error: Cannot find declaration for step path-filtering/filtercci-language-server

I am trying to use CircleCI's path filtering orb to create 2 separate workflows based on which folder in the github repo is modified during future PR/commit.

However CircleCI config validate is showing:
Error: config compilation contains errors: config compilation contains errors: Error calling workflow: 'always-run' Error calling job: 'check-updated-files' Cannot find a definition for command named path-filtering/filter

CircleCI web is showing this error on its website: ERROR IN CONFIG FILE: [#/workflows/always-run] only 1 subschema matches out of 2

This is depsite, exactly following the path-filtering orb documentation example step by step

This is my config.yml code:

version: 2.1

setup: true

orbs:
  path-filtering: circleci/path-filtering@0.1.1
  terraform: circleci/terraform@3.2.1
  aws-cli: circleci/aws-cli@4.1.3v

workflows:
  always-run:
    when:
      or:
        - equal: [ main, << pipeline.git.branch >> ]
        - equal: [ beta, << pipeline.git.branch >> ]
    jobs:
      - path-filtering/filter:
        name: check-updated-files
        base-revision: main
        config-path: .circleci/continue_config.yml
        mapping: |
          lambda/staging/.*: run-lambda-staging-job true
          lambda/production/.*: run-lambda-production-job true

This is the continue_config.yml code:

# workflows, most of which are conditionally

# specific job defined above, in the jobs section.
workflows:

    environment:
      ENV: staging
      ENV_SUFFIX: _staging
    jobs:

      - plan_infrastructure:

            - hold-apply

    environment:
      ENV: production
      ENV_SUFFIX: _production
    jobs:

      - plan_infrastructure:
          name: plan_infrastructure
          requires:
            - project_checkout
      - hold-apply:

          requires:
            - plan_infrastructure
      - apply_infrastructure:
          name: apply_infrastructure
          requires:
            - hold-apply

I tried changing up the syntax, declaring jobs separate from workflow in config.yml and even changing the orb version.

This was a syntax error, solved by parsing the script through a circleci yml checker
