Ollama /api/tags response is missing the `models` key — cann

Error message

Ollama /api/tags response is missing the `models` key — cannot verify embedding model `{model}`. Ollama API may have changed.

What it means

Doctor embedding-model probe: the /api/tags JSON parsed but has no top-level `models` array. Because Ollama's schema is assumed stable, this is reported explicitly as a possible API change rather than misreported as "model not installed". Consequence: the doctor cannot verify whether the configured embedding model is pulled, so it warns and stops rather than producing a false negative.

Solutions

1. Check the Ollama version; if /api/tags changed shape, update Ollama or adjust the probe
2. Confirm you are probing the real Ollama daemon and not another service answering on that port
3. Manually verify with `ollama list` that the embedding model is present
