Kubeflow Pipelines API unable to run Experiment

What steps did you take:

I am following tutorial of Kubeflow Pipelines API: https://www.kubeflow.org/docs/pipelines/tutorials/api-pipelines/.

I am able to create a pipeline ID but each time I want to run that pipeline I get error: {“error”:“invalid character ‘Â’ looking for beginning of object key string”,“message”:“invalid character ‘Â’ looking for beginning of object key string”,“code”:3}

What happened:

I am trying to run experiment using Pipelines API. I am stuck on this error, how do I resolve this error :

curl -H "Cookie: authservice_session=MTY..9l" -H "Content-Type: application/json" -X POST ${SVC}/apis/v1beta1/runs \
-d @- << EOF
{

  "name":"${PIPELINE_NAME}_run",
  "pipeline_spec":{
   "pipeline_id":"${PIPELINE_ID}"
  },
  "resource_references": [
   {
        "key": {
          "type": "EXPERIMENT",
          "id": "20a3bd7f-e1a7-4dad-9389-71bc3122b197"
        },
        "name": "Ajinkya",
        "relationship": "OWNER"
      }
  ]
}
EOF

For this I get error:

{"error":"invalid character 'Â' looking for beginning of object key string","message":"invalid character 'Â' looking for beginning of object key string","code":3}

What did you expect to happen:

I expect the pipeline to start under experiment name : Ajinkya

There was error in my curl request the proper request to run a pipeline ID using cookie is:

curl -H "Cookie: authservice_session=MTY...WQ" -H "Content-Type: application/json" -X POST ${SVC}/apis/v1beta1/runs \
-d @- << EOF
{
  
    "name":"eq_run",
    "pipeline_spec":{
      "pipeline_id":"${PIPELINE_ID}"
    },
    "resource_references":[
      {
        "key":{
          "type":"EXPERIMENT",
          "id":"${EXP_ID}"
        },
         "name": "Default",
         "relationship": "OWNER"
      }
        
      
    ]
}

• For ml-pipeline-api-server kubectl logs ml-pipeline-6bc56cd86d-tf5cb -n kubeflow -c ml-pipeline-api-server I have attached log above.

• For istio-proxy kubectl logs ml-pipeline-6bc56cd86d-tf5cb -n kubeflow -c istio-proxyhere are logs (https://drive.google.com/file/d/1N8vmtfnDb6VnTv-Eas8rTmKWyFTgG2OJ/view?usp=sharing)
