Composio

**Issue:** One of the Hubspot tools has an `associations` parameter declared as `"type": "array"` but missing the required `items` field. Gemini/Vertex AI requires valid JSON Schema where arrays must specify their item type.

**Expected:** `{"type": "array", "items": {"type": "object"}}` (or appropriate item schema)
**Actual:** `{"type": "array"}` (missing `items`)

**Workaround:** Using OpenAI models instead (they're more lenient with schemas)

Update. I thought this would be workaroundable with OpenAI models as were more lenient but that's not the case. 

This doesnt seem to work with any model provider I can find

Isolated it "I think" to the create note tool that seems available in the UI but not on the docs any more? Is that deprecated, will there be a new one? 

Not sure how to proceed here

For now I've patched this myself by adding items to the array field of create notes. 

However suggest this as a bug fix.

Seems to be the same problem with this tool.

Hey <@1254817196266225667>, could you share a reproducible code snippet along with SDK versions? It'll help us in debugging.
