Hey, just signed up and followed the Auth0/Apollo tutorial, but getting CORS errors. What's up? I see similar questions have been asked the last few weeks, but the reply is always "I'll follow up in a PM" (sad face)

@andyblack hey 🙂 good observation
@andyblack :D
a CORS issue can be caused by a lot of things, typically by a malformed query though
a
I've just used this vanilla tutorial: https://github.com/graphcool-examples/react-graphql/tree/master/authentication-with-auth0-and-apollo - I'm 99.99% sure I've filled in all the right credentials, as I can see an auth0 token in the auth0 app and my localstorage
but following the auth0 modal, once I submit the email/name/subscribe form, I'm still not logged in and get 2 errors: 
Error: GraphQL error: The provided idToken is invalid. Please see <https://auth0.com/docs/tokens/id_token> for how to obtain a valid idToken
and 
Fetch API cannot load <https://api.graph.cool/simple/v1/cj463cv4u0e2501219we1y4pk>. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '<http://localhost:3000>' is therefore not allowed access. The response had HTTP status code 504. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

ah ok. did you enter the right credentials in the Graphcool project as well?
also, is the token H256 encoded? you can check on jwt.io pasting the token
a
jwt.io says invalid token
i'll try run the tutorial from scratch again in case i've been a moron somewhere
nope. deleted/recreated everything from scratch, including new graphcool project and auth0 client, but still getting invalid idToken error:
Copy code
Error: GraphQL error: The provided idToken is invalid. Please see <https://auth0.com/docs/tokens/id_token> for how to obtain a valid idToken
    at new ApolloError (apollo.umd.js:1959)
    at apollo.umd.js:2670
    at <anonymous>
(anonymous) @ CreateUser.js:80
on the plus side(!?) not getting the 504s this time...
With the light of day, I dug into my Auth0 settings and flicked to switch to H256, and it's working now - thank you! Has Auth0 recently changed their default encoding algorithm to R256?
n
indeed they did @andyblack 🙂

I have been googling like a mad man for this solution. I should have joined the slack team week ago!
