Retrieving the YAML code for knowledge models using Pycelonis in MLWB

Hi Pratheeksha,

Yes we can retrieve the YAML Code in MLWB

Use this code:

# ── Retrieve a Knowledge Model's YAML and save it in MLWB ──────────────
from pycelonis import get_celonis

celonis = get_celonis()          # uses MLWB env vars automatically

PACKAGE_KEY = "<your_package_key>"   # the Studio package holding the KM

# 1. List the nodes (assets) in the package via the package-manager API
resp = celonis.client.get(
    f"{celonis.url}/package-manager/api/packages/{PACKAGE_KEY}/nodes"
)

# 2. Inspect the structure once so you know the field names
print(resp)

# 3. Pull the KM node's serialized YAML body and write it to disk
for node in resp:
    if node.get("assetType") == "KNOWLEDGE_MODEL":   # adjust if type differs
        yaml_text = node.get("serializedContent", "")
        fname = f"{node.get('key', 'knowledge_model')}.yml"
        with open(fname, "w") as f:
            f.write(yaml_text)
        print(f"Saved: {fname}")

Let me know if you need more support.
