## TL;DR

The field had been added to the OpenAPI spec but the installed SDK was generated from an older spec. `` pip install -U databricks-sdk ` Then pass the mode directly: `python w.clusters.create(..., data\_security\_mode=DataSecurityMode.SINGLE\_USER) `` Use whatever mode your policy requires.

## Steps

1. The field had been added to the OpenAPI spec but the installed SDK was
generated from an older spec. The maintainer confirmed the field is present in
the latest SDK release.

```
pip install -U databricks-sdk
```

2. Then pass the mode directly:

```python
w.clusters.create(..., data_security_mode=DataSecurityMode.SINGLE_USER)
```

3. Use whatever mode your policy requires. If your org pins an old SDK version,
that pin is the bug: the field only exists in the newer generated code.

4. When a documented API field is "missing" from an SDK, check the SDK version
before anything else. Generated SDKs lag the spec, and the fix is an upgrade,
not a workaround.

Expected: The maintainer confirmed the field is present in the latest SDK release.

## When to use

You are seeing this: Calling ClustersAPI.create with data\_security\_mode failed: the attribute was missing from the SDK's generated model. Use this skill when you run into "Databricks SDK: ClustersAPI.create missing data_security_mode".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The field had been added to the OpenAPI spec but the installed SDK was generated from an older spec.
