[Bug] Query entities implementing same interface: Failed to get entities from store: operator does not exist: text = bytea

Empieza reproduciendo las tres consultas GraphQL del issue contra el esquema indicado e inspecciona la consulta PostgreSQL generada y las vinculaciones de tipos en el registro de errores. Rastrea el recorrido de referencias a interfaces a través de la ruta de consultas del store. Se considera terminado cuando las dos consultas anidadas devuelvan las entidades de interfaz esperadas sin el error text = bytea, con cobertura para esta forma de esquema.

Bug report

Current graphql schema looks like this

interface IConfigForProcesses {
    id: ID!
}

type MajorityVotingConfig implements IConfigForProcesses @entity {
    id: ID!

    # flat fields with values
}

type MultiprocessConfig implements IConfigForProcesses @entity {
    id: ID!
    
    # flat fields with values
}

type NominationConfig implements IConfigForProcesses @entity {
    id: ID!

    # flat fields with values
}

type SignatureCollectionConfig implements IConfigForProcesses @entity {
    id: ID!

    # flat fields with values
}

type PetitionCreationConfig implements IConfigForProcesses @entity {
    id: ID!

    # flat fields with values
}

type ElectionActionConfig implements IConfigForProcesses @entity {
    id: ID!

    # flat fields with values
}

type ProcessSpawner implements IAddressable & ITimestamp @entity(immutable: true) {
    id: Bytes!

    staticConfig: IConfigForProcesses

    # flat fields with values
}

type Structure @entity {
    id: Bytes!

    processes: [StructureProcessSpawner!]! @derivedFrom(field: "structure")
}

type StructureProcessSpawner @entity {
    id: Bytes!
    title: String!
    structure: Structure!
    processSpawner: ProcessSpawner!
    timestamp: BigInt!
}

with this kind of structure I've tried three queries

query WORKING_PROCESS_SPAWNERS {
      processSpawners {
        staticConfig {
          id
        }
      }
}

query ERROR_INTERMEDIATE_OBJ_STRUCTURE_PROCESS {
  structureProcessSpawners {
    processSpawner {
      staticConfig {
        id
      }
    }
  }
}

query QUERY_RESULTING_IN_ERROR {
  structures {
    processes {
      processSpawner {
        staticConfig {
          id
        }
      }
    }
  }
}

First query return correct data, but the last two result in error, bubbling up from Postgres.

It does not error when ProcessSpawner.staticConfig is Bytes instead of interface reference, but it defeats the point of using interfaces.

Do you have any ideas why it can be occurring?

From what I've tried already:

• changing id from Bytes to ID and back
• changing running graph-node version from v0.35.0 to v0.34.1
• updating ts packages to the latest versions (@graphprotocol/graph-cli to 0.73.0, 0.35.1)
• cherry-picking starting from the last working commit didn't show any meaningful changes (please contact for more info, cannot share full code publicly)

Tested environments

Local setup:

• OS: mac os
• graph-node in docker container: v0.35.0 and v0.34.1

Remote setup:

• OS: Debian 12
• graph-node in docker container: v0.35.0
