Test failed: ${errorMessage}

Error message

Test failed: ${errorMessage}

What it means

The outer catch of testPrompt: any error thrown during test execution (model call, image understanding, streaming setup) is converted via getSafeTestErrorMessage and re-thrown as TestError prefixed 'Test failed:'. getSafeTestErrorMessage sanitizes messages, particularly when input images are present, to avoid leaking sensitive content.

Solutions

1. Inspect the wrapped message (after 'Test failed:') for the sanitized root cause and fix that (credentials, quota, image format)
2. Retry once for transient network/provider errors
3. Validate image references with the image service before passing inputImages
4. Confirm the model config's API endpoint and credentials are current

Example fix

// before
const out = await promptService.testPrompt(sys, user, modelKey);

// after
try {
  const out = await promptService.testPrompt(sys, user, modelKey);
} catch (e) {
  if (e instanceof TestError) {
    showUserToast(e.message); // sanitized, safe to display
  }
  throw e;
}

null

null

try {
  const out = await promptService.testPrompt(sys, user, modelKey);
} catch (e) {
  if (e instanceof TestError) {
    showUser(e.message); // sanitized by getSafeTestErrorMessage
    if (isTransient(e.message)) retry();
  } else throw e;
}

When it happens

Trigger: Provider API errors (auth, quota, rate limit), network failures, image-understanding service errors when inputImages are provided, or invalid model responses during the test call — all caught and wrapped here.

Common situations: Running a quick test with an invalid API key; oversized/unreadable image inputs triggering image-service failures; transient provider outages during manual testing.
