This is my talk at GraphQL Finland 2018 (https://graphql-finland.fi) that gives both an overview of patterns being used
to surface errors that occur during GraphQL query execution, as well as what our (artsy.net) approach is.
You can find all original materials in this repo https://github.com/alloy/graphql-finland.
Finally, you can find a blog post version here (http://artsy.github.io/blog/2018/10/19/where-art-thou-my-error/), where
you can also leave comments with your feedback on all of this 🙏
