Authorization error when updating a GraphQL object using aws-amplify - graphql

Question

I'm experiencing issues when using aws amplify to generate a graphql API
My model has mainly two objects (User and messages):
User object:
type User
#model(subscriptions: null)
#auth(rules: [{ allow: owner, ownerField: "id" }]) {
id: ID!
email: String!
username: String!
avatar: S3Object
name: String
conversations: [Conversation] #manyToMany(relationName: "UserConversations")
messages: [Message!]! #hasMany(indexName: "byAuthor", fields: ["id"])
createdAt: String
updatedAt: String
}
Message object:
type Message
#model(subscriptions: null)
#auth(
rules: [
{
allow: owner
ownerField: "authorId"
operations: [create, update, delete]
}
]
) {
id: ID!
author: User #belongsTo(fields: ["authorId"])
authorId: ID! #index(name: "byAuthor", sortKeyFields: ["content"])
content: String!
conversation: Conversation! #belongsTo(fields: ["messageConversationId"])
messageConversationId: ID!
#index(name: "byConversation", sortKeyFields: ["createdAt"])
createdAt: String
updatedAt: String
}
There's a hasMany/belongsTo relationship between the two and auth rules on both.
After I signin to the API and try to create a user object through the JS API, i'm getting the following error
'Not Authorized to access messages on type ModelMessageConnection'
await AuthAPI.graphql(
graphqlOperation(createUser, {
input: {
id,
username,
email,
name,
},
})
);

This is actually due to the message rule that was missing the read action. Changing the object model to the code below fixed it
type Message
#model(subscriptions: null)
#auth(
rules: [
{
allow: owner
ownerField: "authorId"
operations: [create, update, delete, read]
}
]
) {
id: ID!
author: User #belongsTo(fields: ["authorId"])
authorId: ID! #index(name: "byAuthor", sortKeyFields: ["content"])
content: String!
conversation: Conversation! #belongsTo(fields: ["messageConversationId"])
messageConversationId: ID!
#index(name: "byConversation", sortKeyFields: ["createdAt"])
createdAt: String
updatedAt: String
}
