completion assistant search is not supported for this reques

Error message

completion assistant search is not supported for this request

What it means

This error is raised by completionAssistantSearchTypeMembers when the completion-assistant request asks for type-member completions but the request is not actually a type-members search: parentName is empty or the requested object kinds do not include type members (xuguCompletionRequestsTypeMembers returns false). It guards against mis-routed completion requests.

Solutions

1. Set parent_name in the request to the qualified name of the parent type
2. Ensure object_kinds includes the type-members kind so the request routes correctly
3. Verify the client is calling the correct completion endpoint for its request type
4. If parent_schema is also needed, supply it (or ensure schema is set) to pass subsequent checks

Example fix

// before
req := completionAssistantRequest{ObjectKinds: kinds} // parent_name missing
// after
req := completionAssistantRequest{ObjectKinds: kinds, ParentName: "my_schema.my_type"}

// Validate the completion request before calling the assistant
if strings.TrimSpace(req.ParentName) == "" || !xuguCompletionRequestsTypeMembers(req.ObjectKinds) {
    return errors.New("type-member completion requires parent_name and type-members object_kinds")
}

func supportsTypeMembersSearch(r completionAssistantRequest) bool {
    return strings.TrimSpace(r.ParentName) != "" && xuguCompletionRequestsTypeMembers(r.ObjectKinds)
}

resp, err := s.completionAssistantSearchTypeMembers(req)
if err != nil && strings.Contains(err.Error(), "not supported for this request") {
    // fall back to the generic completion search path
    resp, err = s.completionAssistantSearchDefault(req)
}

When it happens

Trigger: Calling the completion assistant with a request whose ParentName is blank while ObjectKinds indicate (or fail to indicate) Xugu type-member completion, i.e. the request shape does not match the type-members search path.

Common situations: Client sends completion requests without setting parent_name when completing members of a Xugu structured/object type; a generic completion UI reuses the type-members endpoint for non-type requests; API version mismatch changing ObjectKinds values.
