Meteor url must be absolute and start with http:// or https://

As soon a i do a post request on my server side i get this error

[Error: url must be absolute and start with http:// or https://]

I have set app.use(’*’, cors({ origin: ‘http://localhost:8100’, credentials: true }));

don’t know what’s i’m doing wrong

How do you do a post request to your meteor server? Are you using the Webapp directly? I think this error is from the post request itself
