Bug report: Cannot return null for non-nullable field on subscription_root

[revskill10]

I'm using graphql-yoga and use transformSchema to rename root query for a remote schema.
The query works fine. But for subscription, i got the error : Cannot return null for non-nullable field on subscription_root.table_name
The function to rename is

function renameSchema(remoteExecSchema, prefix) {
  return transformSchema(
    remoteExecSchema,
    [
      new RenameTypes((type) => `${prefix}_${type}`),
      new RenameRootFields((operation, name) => `${prefix}_${name}`)
    ]
  );
}

I think this is related to ardatan/graphql-tools#997

@revskill10, Did you find a workaround?

@wawhal Can we figure out if it is an issue with apollo and send a PR to them if that's the case?

I could replicate this. Working on a fix.

Tracked here. Please add a thumbs up so that it gains priority :-)

@Maxpain177 Till now, my strategy is to untrack tables which has duplicated name, then i create a view with different name. That's why i created the related issue here, which allows untracking multiple tables at once.
