Answer 1

According with docs, when we need to create Fields as Array or List, the directive @scalarlist directive is required, in your case the correct model definition should be with the table/column imgs

type Event {
  id: ID! @id
  owner: User! @relation(name: "HostedEvents")
  name: String!
  imgs: [String!]! @scalarList(strategy: RELATION)
  description: String
  start: DateTime!
  end: DateTime!
  categories: [Category]!
  members: [User]! @relation(name: "EventMembers")
  chatRoom: GroupChatRoom!
  pendingRequests: [PendingRequest]!
  locations: [Location]!
  comments: [Comment]!
  createdAt: DateTime! @createdAt
  updatedAt: DateTime! @updatedAt
}
