Hey team 👋 — running into what looks like a dashboard bug and wanted to flag it. Bug: When editing the System Prompt on an assistant that has a knowledgeBase attached, the dashboard automatically injects

"model": "gemini-2.5-flash"

into the knowledgeBase object on save. This then causes the publish to fail with the error: >

model.each value in knowledgeBase.property model should not exist

So the dashboard is injecting a field that the API itself rejects — making it impossible to save any prompt changes through the UI. Steps to reproduce: 1. Create an assistant with a knowledgeBase file attached 2. Edit the System Prompt 3. Click Publish 4. Error appears:

model.each value in knowledgeBase.property model should not exist

5. Inspect the payload —

"model": "gemini-2.5-flash"

has been auto-injected into the knowledgeBase object Is this a known issue? Any timeline for a fix? Thanks!
