UNSUPPORTED_TEST_TYPE

Error message

UNSUPPORTED_TEST_TYPE

What it means

The Ollama image adapter's getTestImageRequest supports only its defined test types; any other testType throws UNSUPPORTED_TEST_TYPE with the value in metadata. Mirrors the same pattern as other adapters.

Solutions

1. Use the supported text-to-image test type for Ollama models
2. Gate test options by provider capability in the calling UI
3. Contribute support if Ollama adds the capability

const OLLAMA_TESTS = new Set(['text2image'])
if (provider === 'ollama' && !OLLAMA_TESTS.has(testType)) return skip()

function ollamaSupportsTest(t: string): boolean { return t === 'text2image' }

if (!ollamaSupportsTest(testType)) return
await adapter.getTestImageRequest(testType)

When it happens

Trigger: Running a model connectivity test with an unsupported testType against an Ollama-hosted image model — e.g. an edit or i2i test type, since Ollama's image API is text-to-image only.

Common situations: Generic test harnesses enumerating all test types; Ollama's experimental OpenAI-compatible image API lacking endpoints for the requested test kind.
