Я тестирую плагин Neo4j GraphQL.У меня есть схема IDL, которую я передаю Neo4j:
CALL graphql.idl(
'type Address {
id: ID!
display_name: String
adress_spec: AddrSpec!
adress_from: Originator! @relation(name: "From")
adress_sender: Originator @relation(name: "Sender")
adress_reply_to: Originator @relation(name: "ReplyTo")
destination_to: [Destination] @relation(name: "To")
destination_cc: [Destination] @relation(name: "Cc")
destination_bcc: [Destination] @relation(name: "Bcc")
}
type Originator {
id: ID!
origin_date: Datetime!
originator_role: originator_role!
message: [Message!] @relation(name: "Originator")
address_from: Address! @relation(name: "From")
address_sender: Address @relation(name: "Sender")
address_reply_to: Address @relation(name: "ReplyTo")
}
type Destination {
id: ID!
destination_role: destination_role!
received_date: Datetime!
message: Message! @relation(name: "Destination")
address_to: [Address]! @relation(name: "To")
address_cc: [Address] @relation(name: "Cc")
address_bcc: [Address] @relation(name: "Bcc")
}
type Message {
id: ID!
subject: String
comments: String
originator: Originator! @relation(name: "Originator")
destinations: [Destination]! @relation(name: "HasDestination")
referencing: [Message] @relation(name: "Referencing")
in_reply_to: [Message] @relation(name: "InReplyTo")
keywords: [Keyword] @relation(name: "Tags")
}
type Keyword {
id: ID!
keyword: String!
messages: [Message] @relation(name: "Tags")
}
');
И я получаю описание интерфейса:

Однако в GraphiQL нет описания схемы и вNeo4j Я получаю сообщение об ошибке:
call graphql.schema()
Результат:
Neo.ClientError.Procedure.ProcedureCallFailed: не удалось вызвать процедуру graphql.schema: вызвано: kotlin.KotlinNullPointerException
Есть предложения?
