X_NAVIGATION_MODAL_PATH_INVALID
Means
openModal was given something that is not a path of this origin
Typical cause
openModal(path) addresses a modal by the hash '#<path>', so path must be an absolute path on this origin starting with a single '/' — a URL of another origin, a protocol-relative '//host' or a relative 'new' names no modal
Fix
openModal('/runs/new') — the modal route's own path, as its link carries it; never a full URL or a relative one
