CORS problem when fetching from local app

Hi Everyone!
I’m trying to create a webhook from a local app, but I always get a Error 400 response:

Access to XMLHttpRequest at '' from origin 'https://localhost:5173' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Does anybody know how I can prevent the cors error?
Many thanks in advance for any help! :bouquet:

Hi @Kaj_Lehmann,
Are you using remoteFetchAsync?
