graphiql doesnt work: "Cannot serve request to /content/graphiql/ in org.apache.sling.servlets.get.DefaultGetServlet"

[TB3dock]

I installed graphiql according to this article

Here we can see the package is installed:

But when I go to the required url:

http://localhost:4502/content/graphiql.html

I get:

Forbidden

Cannot serve request to /content/graphiql/ in org.apache.sling.servlets.get.DefaultGetServlet

I am installing on a fresh instance of the AEM cloud SDK, with a clean install of the wknd site directly from git (which has grapql endpoint configured etc)

Any ideas? The tutorial has no additional configuration that I can see.

I also tried "reinstall"

Here is the complete output.

Hi, did you find any solution for this? Thanks

[TB3dock]

Interestingly, the problem was cors.  I was using a chrome plugin, which, even though running on local host failed chrome cors check.

I switched to hitting the graphql endpoint from postman, and problem solved (for local host at least). 

Due to he missing features and non-standard and poorly documented syntax in the AEM graphQL implementation, we abandoned it, and use servlets + queryBuilder instead.

Performance with queryBuild is not that great, even with low number of content items, so we are thinking of writing our own in memory content cache and our own query language.
