Failed to create collection (${response.status}).

Error message

Failed to create collection (${response.status}).

What it means

Thrown by useCreateMarketplace when the POST that creates a collection (marketplace) returns a non-ok HTTP status. getRequestError extracts the server's error message from the JSON payload, falling back to 'Failed to create collection (<status>)'. It indicates the server refused collection creation before any response parsing could occur.

Solutions

1. Check the status in the message: for 401/403, re-authenticate or obtain marketplace-create permission for the org.
2. For 400/409/422, fix the submitted name/description (uniqueness, length) and resubmit.
3. For 5xx, retry with backoff and check Den server health.
4. Surface isReauthRequiredError to trigger the re-auth flow rather than a generic toast.

Example fix

// before
await createMutation.mutateAsync({ name });
// after
try {
  await createMutation.mutateAsync({ name });
} catch (err) {
  if (isReauthRequiredError(err)) { startReauth(); }
  else setCreateError(err.message);
}

// before createMutation.mutateAsync
const name = input.name?.trim();
if (!name) throw new Error("Collection name is required");
if (name.length > 120) throw new Error("Collection name is too long");
if (existingNames.has(name)) throw new Error("A collection with this name already exists");

function isReauthError(err: unknown): err is ReauthRequiredError {
  return err instanceof ReauthRequiredError;
}

try {
  await createMutation.mutateAsync(input);
} catch (err) {
  if (isReauthRequiredError(err)) startReauth();
  else setFormError(err.message);
}

When it happens

Trigger: Non-ok response from POST /v1/marketplaces (15000ms timeout): 401 when not signed in, 403 when the user lacks marketplace-create permission in the org, 400/422 when name/description violate server validation (duplicate name, length limits), 409 on name conflicts, 5xx on server faults.

Common situations: User session expired; org role downgraded so creating collections is forbidden; duplicate collection name; oversized description; Den server errors during deployments.
