Neo4j-graphql-js: Error in version 2.19.1, GraphQLError: Argument "direction" has invalid value "OUT"

[CostaFernando]

Hi guys,

I just updated my neo4j-graphql.js version from 2.18.0 to 2.19.1. But now, when I try to run npm start, I get this error:

> [email protected] start /home/fernando/Code/jovens-genios/services/graphql-api
> npm run build && node build/index.js


> [email protected] build /home/fernando/Code/jovens-genios/services/graphql-api
> babel src --out-dir build && shx cp .env build 2>/dev/null || : && shx cp -r src/types/ build

Successfully compiled 11 files with Babel (617ms).

If I rollback to neo4j-graphql.js 2.18.0, it runs correctly. I think this is related to "graphql-tools": "^7.0.2" as dependency.

This is my package.json:

Hi! Ran into the same thing running the sample, remove the quotes around IN and OUT and you should be fine.
PR that made the change -> https://github.com/neo4j-graphql/neo4j-graphql-js/commit/c9b8b1af65ea751d060be79f8ab9d521577968de

So, your relation ship should NOT look like this:
@relation(name: "IN_GENRE", direction: "OUT")
But rather like this:
@relation(name: "IN_GENRE", direction: OUT)

Removing the double quotes made it work for me.

It worked! Thank you, @SebSaveBySolar !
