[type error] <details> <summary><b>Severity Level:</b> Major ⚠️</summary> ```mdx - ❌ Persistent storage writes can fail with internal errors. - ⚠️ Extensions receive 5xx instead of actionable validation message. ``` </details> <details> <summary><b>Steps of Reproduction ✅ </b></summary> ```mdx 1. Start Superset with this PR and authenticate a user. 2. Call `PUT /api/v1/extensions/test.publisher/testext/storage/persistent/foo` (handled by `ExtensionStorageRestApi.set_persistent` in `superset/extensions/storage/api.py:571-687`). 3. Send JSON body `["value"]` with `Content-Type: application/json`, so `request.get_json(silent=True)` at line 645 returns a list. 4. At lines 645-649, `"value" in body` succeeds, then `body.get("codec", DEFAULT_CODEC)` raises `AttributeError`, causing a 500 response instead of a 400. ``` </details> [](https://app.codeant.ai/fix-in-ide?tool=cursor&prompt_id=323b162ca26544849382ef5bd5a2f182&service=github&base_url=https%3A%2F%2Fgithub.com&org=apache&repo=apache%2Fsuperset) [](https://app.codeant.ai/fix-in-ide?tool=vscode-claude&prompt_id=323b162ca26544849382ef5bd5a2f182&service=github&base_url=https%3A%2F%2Fgithub.com&org=apache&repo=apache%2Fsuperset) *(Use Cmd/Ctrl + Click for best experience)* <details> <summary><b>Prompt for AI Agent 🤖 </b></summary> ```mdx This is a comment left during a code review. **Path:** superset/extensions/storage/api.py **Line:** 645:649 **Comment:** *Type Error: The same body-shape bug exists in persistent writes: non-dict JSON can pass the membership check and then fail on `body.get`, causing a 500 instead of a client error.
