No provider or model selected

Error message

No provider or model selected

What it means

saveForm throws 'No provider or model selected' when canSaveForm is false, i.e. the form lacks a providerId or a usable model id. It is a pre-flight validation error preventing an invalid model config from being persisted.

Solutions

1. Ensure providerId and modelId are set before calling saveForm (disable the save button unless canSaveForm is true)
2. If using a custom model, fill in the modelId field; check that canSaveForm's conditions match your provider type (some providers need no key)
3. Await provider loading so providerId can be assigned programmatically
4. Add inline form validation messages so the reason canSaveForm is false is visible

Example fix

// before
if (!canSaveForm.value) {
  throw new Error('No provider or model selected')
}

// after
if (!canSaveForm.value) {
  throw new Error(
    !form.value.providerId ? 'No provider selected' : 'No model selected'
  )
}

if (!form.value.providerId || !form.value.modelId) {
  // disable save / show field errors; do not call saveForm
}

const isFormSubmittable = (f: { providerId?: string; modelId?: string }): boolean =>
  Boolean(f.providerId && f.modelId)

try { await saveForm() } catch (e) { if (String(e?.message) === 'No provider or model selected') { focusFirstMissingField() } else throw e }

When it happens

Trigger: Clicking save before selecting a provider, or before choosing/typing a model id; custom-model mode where the modelId input is still empty; canSaveForm computed incorrectly evaluating false due to a missing dependent field.

Common situations: Save button enabled while async provider list is still loading; user types a custom model name but the debounced modelId update hasn't committed; validation computed requires apiKey that is empty for keyless providers.
