knowledge_base_id is required

Error message

knowledge_base_id is required

What it means

CreatePage requires the page to reference a knowledge base; when page.KnowledgeBaseID is empty the service returns this error. Without the KB association the page cannot be scoped, listed, or have its slug uniqueness enforced within the right namespace.

Solutions

1. Populate page.KnowledgeBaseID from the request/route context before calling CreatePage.
2. Validate knowledge_base_id is present at the handler boundary and return 400 otherwise.
3. Verify the JSON tag/field name used by request binding matches what clients send.

Example fix

// before
page := &types.WikiPage{Slug: slug, Title: req.Title}
// after
page := &types.WikiPage{Slug: slug, Title: req.Title, KnowledgeBaseID: kbIDFromRequest}

if strings.TrimSpace(page.KnowledgeBaseID) == "" {
    return httpError(400, "knowledge_base_id is required")
}

When it happens

Trigger: Calling CreatePage with page.KnowledgeBaseID == "" — e.g. the request did not include the KB id, or a route param failed to bind into the WikiPage struct.

Common situations: Client omits knowledge_base_id in the create payload; endpoint refactor renamed the field so binding now leaves it empty; scripts creating pages across KBs forgetting the association.
