This is a confirmed bug that has already been fixed. It occurs because when you disable "Summary Generation Auto," the frontend sends summary_index_setting with null field values (e.g., {"enable": null, "model_name": null, ...}) instead of either omitting the object or setting it to null entirely. The strict Pydantic v2 validation then rejects these None values [1].

Fix status: PR #36355 (merged) covers this in the Knowledge Pipeline workflow path, and PR #36626 (merged) fixes it in the dataset service estimate models. Both should be available in the next tagged release after v1.14.2 [2].

Workaround until you upgrade: In your pipeline/dataset settings, set summary_index_setting to null entirely (not an object with null fields), or provide empty strings: {"enable": false, "model_name": "", "model_provider_name": "", "summary_prompt": ""} [1]. Alternatively, toggling the summary setting on then off again and saving can force the values into a valid state [3].
