## Summary A Dag that declares a nullable `Param` and leaves it unset can no longer submit a Databricks run: the params are auto-forwarded into each task's dict-shaped parameter slot, and the `None` fails payload validation before any API call. A param with no value is nothing to forward, so it is now skipped. `DatabricksRunNowOperator` and `DatabricksCreateJobsOperator` forward Dag params the same way but inject after validation, so there the `None` reached the Databricks API as `null` instead of failing locally; all three now filter identically. closes: #71776 --- ##### Was generative AI tooling used to co-author this PR? - [X] Yes — Claude Code (Opus 5) Generated-by: Claude Code (Opus 5) following [the guidelines](https://github.com/apache/airflow/blob/main/contributing-docs/05_pull_requests.rst#gen-ai-assisted-contributions) -- This is an automated message from the Apache Git Service.
