hailo-ollama works for plain chat, but fails (HTTP 500 error) when the request includes tools or a JSON-schema object in format. This prevents using hailo-ollama with Home Assistant Assist, which sends these fields.
Plain chat OK:
curl -sS -X POST "http://<host>:8000/api/chat" -H "Content-Type: application/json" -d '{
"model":"llama3.2:1b",
"messages":[{"role":"user","content":"hello"}],
"stream":false
}'
format schema → 500:
curl -sS -X POST "http://<host>:8000/api/chat" -H "Content-Type: application/json" -d '{
"model":"llama3.2:1b",
"messages":[{"role":"user","content":"Return {\"greeting\":\"...\"} and nothing else."}],
"stream":false,
"format":{"type":"object","properties":{"greeting":{"type":"string"}},"required":["greeting"]}
}'
tools → 500:
curl -sS -X POST "http://<host>:8000/api/chat" -H "Content-Type: application/json" -d '{
"model":"llama3.2:1b",
"messages":[{"role":"user","content":"Call the tool."}],
"stream":false,
"tools":[{"type":"function","function":{"name":"demo_tool","description":"Returns a fixed string","parameters":{"type":"object","properties":{},"required":[]}}}]
}'
Error includes: TreeToObjectMapper::mapString(): Node is NOT a STRING.
Feature request: implement Ollama-compatible tool calling + JSON-schema structured outputs (object format) so Assist integrations work.
Thanks.
