app.use(body({
        multipart: true,
        jsonLimit: '1mb',
        formLimit: '56kb'
}));

hm, I'll check it, sorry.

[tunnckoCore]

@Echobob could you provide exact code that you trying? Use case, post data, request lib, middlewares?
Tests passes, wtf... lol

[tunnckoCore]

Maybe the reason is that the request is not json/urlencoded/multipart, and goes to L90 col 61, which is multipart.fields and it is normally to be undefined, cuz i forgot to set else {return yield next} if not pass some of the given conditions

app.use(function *() {

});

The error is happening when there is a CSP error and the browser sends a post request to /api/csp
It never goes past better-body.

[Echobob]

The Content Type header is application/csp-report, but is equivalent to application/json

[tunnckoCore]

Oh yea, this is the reason, normal to cause problems. I'm not so familiar with all this new stuff headers, policies and etc.
Could you give some ref to read that they are equivalents?
