The culprit here is description on schema directive:

# generated by absinthe 1.5
schema {
  query: RootQueryType
  mutation: RootMutationType
}

...

# generated by absinthe 1.6
"Represents a schema"
schema {
  query: RootQueryType
  mutation: RootMutationType
}

...

"Represents a schema" is newly inserted line, which causes error.

In graphql spec I assume everything is describe-able, so I believe this is a valid schema file, but no confidence here.

Which part of the generator needs looking? Or, should this be reported to Absinthe as inconsistency?

Any guidance is appreciated.

For now I'm dropping first line of the generated file with | tail -n +2 as a cheap workaround.

Hello! This is using the NPM package graphql under the hood. It looks like they added support for this syntax in their 15.0.0 release through this PR graphql/graphql-js#2419.

I think if I merge this pull request from dependabot it should fix it: #446.

Maybe I can add a little test case to try it out in the end-to-end tests after merging this in. Thanks for reporting the issue!

[dillonkearns]

Published! I believe this should be working in the latest NPM release: https://github.com/dillonkearns/elm-graphql/blob/master/CHANGELOG-NPM-PACKAGE.md#411---2021-02-04.

Could you try it out and confirm that it's working for you without the workaround now? Thank you!

[ymtszw]

Quickness 👍
And it worked, thanks.
