Hi,
I've been trying to use inferSchema and makeAugmentedSchema on what will be a GRANDstack application.

Whether I use the GRANDstack template or my own code, inferSchema produced a good output and makeAugmentedSchema produced a series of errors.

Here is a basic overview of my structure:

  "dependencies": {
    "apollo-server": "^2.10.0",
    "apollo-server-express": "^2.10.0",
    "cypher-tagged-templates": "^3.0.0",
    "dotenv": "^8.2.0",
    "neo4j-driver": "^4.0.1",
    "neo4j-graphql-js": "^2.12.1",
    "nodemon": "^2.0.2"
  }

EDIT: Note: I was using "from: date" as properties on many of the relations to provide versioning, and since the error was plastered with .from, I renamed this property to "startDate" and re-ran everything. It worked!
Note to self, "from" is a reserved property for relations.

Here is the error from makeAugmentedSchema():

C:\Github\dev\node_modules\graphql\validation\validate.js:108
    throw new Error(errors.map(function (error) {

Here is the relevant part of the inferred schema: Notice the duplicate "from"s.

type HAS_PRIMARY_DOMAIN @relation(name: "HAS_PRIMARY_DOMAIN") {
  from: Competency!
  to: Domain!
  from: String!
}

  from: Competency!
  to: TargetCompetency!
  from: String!
}

  from: Competency!
  to: AssessmentCriteria!
  from: String!
}

  from: Competency!
  to: ShortName!
  from: String!
}

[SOLVED] makeAugmentedSchema() doesn't play well if "from" is used as a property of a relation
