Filters: { dateFormat:

Question

Filters: { dateFormat:

function(value) {
if (!value) return ''
return value + '1'
}
}

_____
<p>{{match.DateMatch | dateFormat}}</p>

runtime-core.esm-bundler.js?5c40:38 [Vue warn]: Property "dateFormat" was accessed during render but is not defined on instance.
at <MatchFuture>
at <Home onVnodeUnmounted=fn<onVnodeUnmounted> ref=Ref< Proxy {…} > >
at <RouterView>
at <App>

И выводит везде в p только 0. Почему так?
