Getting

[anantkharat]

payload = {

"clusters": [

{

"num_workers": 4

}

],

"pipeline_id": pipeline_id

}

update_url = f"{workspace_url}/api/2.0/pipelines/{pipeline_id}"

response = requests.put(update_url, headers=headers, json=payload)

for this, i'm getting below output with status code 400.
{"error_code":"INVALID_PARAMETER_VALUE","message":"Cannot modify catalog of an existing pipeline. Existing catalog: 'doha'. Requested catalog: ''"}

i also have tried with 

url = f"{workspace_url}/api/2.0/pipelines/{pipeline_id}"

response = requests.get(url, headers=headers)

response.json()

using above response and modifying the num_workers, without changing any catalog parameter and also with catalog parameter same as previous. but still getting same error..

kindly help

Hi @anantkharat ,

Can you please try something like 
pipelines.update(pipeline_id, configuration=configuration, catalog='doha')

From the error message it says catalog was empty.

Check this section https://docs.databricks.com/api/workspace/pipelines/update#catalog

A catalog in Unity Catalog to publish data from this pipeline to. If target is specified, tables in this pipeline are published to a target schema inside catalog (for example, catalog.target.table). If target is not specified, no data is published to Unity Catalog.

Thanks!
