reactjs - ScriptExternalLoadError: Laddning av skript misslyckades. - Modul Federation: React + Typescript

Jag försöker köra grundläggande MF-appar med React + Typescript.

använde create-mf-app för att generera boilerplate-kod. Ovanpå det lade jag bara till en komponent Cookie.tsx. Det finns ingenting där. Bara en p-tagg.

Jag får nedanstående problem som jag inte kan hitta en lösning på.

ERROR
Loading script failed.

while loading "./Cookie" from webpack/container/reference/app1
