Trigger pipeline in another repo

Question

Trying to trigger a pipeline in another repo

The triggering repo has this for its bitbucket-pipelines.yml

options:
  docker: true
pipelines:
  pull-requests:
  '**': #trigger pipeline in gemm_fw
    - step:
      script:
        - pipe: atlassian/trigger-pipeline:5.0.1
          variables:
            BITBUCKET_USERNAME: 'bsteinic'
            BITBUCKET_APP_PASSWORD: 'app-password generated'
            REPOSITORY: 'gemm_fw'
            REF_TYPE: 'branch'
            REF_NAME: 'master'
            #CUSTOM_PIPELINE_NAME: 'pull-requests'
            # [{
            # "key": "BITBUCKET_BRANCH",
            # "value": "${BITBUCKET_BRANCH}"
            # }]
            DEBUG: 'true'
            WAIT: 'true'

Fails with the following:

DEBUG: Starting new HTTPS connection (1): bitbucket.org:443
DEBUG: https://bitbucket.org:443 "GET /bitbucketpipelines/official-pipes/raw/master/pipes.prod.json HTTP/1.1" 200 None

"So is there a way to trigger a pull-requests entry pipeline build when there is not a created pull-request?"

According to pipelines config page: 
"If you already have branches in your configuration, and you want them all to only run on pull requests, replace the keyword branches with pull-requests."

So if you don't want to create pull requests, just use branches instead of pull-requests

If I add a section to the bitbucket-pipelines.yml file the build is triggered successfully triggered:

branches:
    test-branch:
      - step:
          name: Unit Test Pipeline
          script:
              - ...

Changed the request to be "ref_name": "test-branch"

So is there a way to trigger a pull-requests entry pipeline build when there is not a created pull-request?

pipelines:
  pull-requests:
    '**': #runs as default for any branch not elsewhere defined
    - step:
      script:

Looks like the same failure:

curl -X POST -is -u uname:app-password -H 'Content-Type: application/json' https://api.bitbucket.org/2.0/repositories/tdwilliamson_EE/gemm_fw/pipelines/ -d '
