${response.error || "Failed to create system prompt"}

Error message

${response.error || "Failed to create system prompt"}

What it means

Thrown from `createSystemPrompt` on a non-ok `POST /api/community-hub/system-prompt/create`. Reads `response.error`, falling back to 'Failed to create system prompt'. Validation 4xx is the most common cause: the prompt payload (name, visibility, prompt text, tags) must satisfy the hub schema.

Solutions

1. Validate the payload shape client-side (non-empty name+prompt, visibility ∈ {public,private}, tags array).
2. Read `error` from the returned `{ success, error }` for the precise reason.
3. On 401 re-authenticate; on 409 rename the prompt.
4. Trim fields and enforce tag count/length limits before posting.

Example fix

// before
await CommunityHub.createSystemPrompt(formData);

// after
const payload = {
  name: String(formData.name).trim(),
  prompt: String(formData.prompt).trim(),
  visibility: ['public','private'].includes(formData.visibility) ? formData.visibility : 'private',
  tags: Array.isArray(formData.tags) ? formData.tags.slice(0, 10) : [],
};
if (!payload.name || !payload.prompt) throw new Error('Name and prompt are required');
const { success, error } = await CommunityHub.createSystemPrompt(payload);
if (!success) throw new Error(error || 'Failed to create system prompt');

function validateSystemPromptPayload(data) {
  const name = String(data?.name || '').trim();
  const prompt = String(data?.prompt || '').trim();
  const visibility = data?.visibility;
  if (!name) throw new Error('System prompt name is required');
  if (!prompt) throw new Error('System prompt text is required');
  if (!['public','private'].includes(visibility)) throw new Error("visibility must be 'public' or 'private'");
  if (!Array.isArray(data?.tags)) throw new Error('tags must be an array');
}

function isSystemPromptPayload(v) {
  return !!v && typeof v === 'string' && typeof v.name === 'string' && typeof v.prompt === 'string'
    && ['public','private'].includes(v.visibility) && Array.isArray(v.tags);
}

const { success, error, itemId } = await CommunityHub.createSystemPrompt(data);
if (!success) showToast(error || 'Failed to create system prompt');

When it happens

Trigger: Missing required fields (name/prompt/visibility), invalid `visibility` value (not 'public'/'private'), tags not an array or over the limit, 401 non-admin, 409 duplicate name, 500 persistence failure.

Common situations: Submitting an incomplete form; visibility typo; too many/oversized tags; session expired before submit.
