Unable to load data in Dgraph while following tour.dgraph.io

Moved from GitHub tutorial/86

Posted by ashish-goswami:

While going through https://tour.dgraph.io/, I was trying to to load data by clicking run on page https://tour.dgraph.io/master/intro/4/#. I found it is not working for chrome/firefox. Found following errors:

Chrome: TypeError: Bootstrap tooltips require Popper.js (https://popper.js.org)
Firefox: TypeError: NetworkError when attempting to fetch resource.

I also observerd, POST call to Dgraph server was hitting different endpoints:
Chrome: http://localhost:8080/mutate?commitNow=true
Firefox: http://localhost:8080/commit?startTs=0&abort=true

Hey @paulftw could you have a look at this?

prashant-shahi commented :

PR #87 should resolve this issue.

Also looked into the endpoints being hit across 3 different browsers. They don’t seem to differ now.

Browser Version Endpoint
Chrome 75.0.3770.100 http://localhost:8080/mutate?commitNow=true
Firefox 68.0.1 http://localhost:8080/mutate?commitNow=true
Opera 62.0.3331.99 http://localhost:8080/mutate?commitNow=true

Fixed in the latest version of tour.
master version of the tour should be used when dgraph 1.1 is running locally.
dgraph 1.0.16 version of the tour is for users with pre-1.1 dgraphs.
An alert about the version mismatch is on the roadmap

I have the same error in Safari for mac in step #3.

I get
TypeError: Not allowed to request resource
for this link:
It works in Chrome.
