Sample application
Show stacktrace when ssr error happens, and no error being passed to component...
Pre-requisites
yarn
File structure
- graphql server having a good and bad query resolved
- page page showing the bug happening
- bad component component having the bug
- apollo client with this settings error will not be thrown, BUT also not passed to component!
Development
yarn dev- goto http://localhost:3000/ (playground at http://localhost:3000/api/graphql)
Now you will see the following stack:
[client] render good
[client] render bad
[server] GraphQL server query: bad (query, once)
[server] GraphQL server query: good (query, once)
[GraphQL error]: Message: oeps, Location: [object Object], Path: bad
[client] render good (nextjs rendering again)
[client] render bad (nextjs rendering again)
Now the error is not passed to its component. When i change the errorPolicy in the above apollo client not to 'all', since i want to be able to use the error, i get the following stacktrace:
[client] render good
[client] render bad
[server] GraphQL server query: good
[server] GraphQL server query: bad
[GraphQL error]: Message: oeps, Location: [object Object], Path: bad
[GraphQL treewalker error] Error GraphQL error: oeps
[server] GraphQL server query: bad
Now you can see the treewalker throws the error (which i catch), but then client-side the call is done again... And that part should not happen, but its unclear for me with what settings.
Repo is created for apollographql/react-apollo/issues/3918, to show in codesandbox.io the bug
