Subgraph on hosted service issue with selecting based on an ethereum address

Question

I have created the schema for my subgraph inside the .graphql file, here is a sample: `

type Post @entity {
  id: ID!
  title: String! # string
  body: String! # string
  createdAt: BigInt! # uint256
  groupID: BigInt! # uint256
}

type User @entity {
  id: ID! 
  userId: BigInt!
  transactionHash: Bytes
  telephoneVerifiedData: String
  email: String # string
  _userAddress: Bytes
}

`

I tried making a schema for the query treating _userAddress field as a plain text (I don't know any other way, can't find anything in the docs):

type _Schema_
  @fulltext(
    name: "getUser"
    language: simple
    algorithm: rank
    include: [
      { entity: "User", fields: [{ name: "userName", name: "_userAddress" }] }
    ]
  )

but I get this message when deploying the subgraph:

✖ Failed to deploy to Graph node https://api.thegraph.com/deploy/: deployment failure::subgraph validation error: [schema validation failed: [FulltextIncludedFieldInvalid("_userAddress")]]

Answer 1

I see two issues.

In the fulltext query you specify userName as a field to search but it isn't defined on your User entity. Add userName: String to your User entity and

Second, the type of _userAddress is Bytes. In order for this field to be search it needs to be of type String.
