NGram translates to Ngram: ReferenceError: Ngram is not defined

Help

I have the following:

CreateIndex({
  name: 'searchUsersByName',
  terms: [
    { binding: 'search' }
  ],
  source: {
    collection: Collection('users'),
    fields: {
      search: Query(
        Lambda(
          ['row'],
          Union(
            NGram(
              LowerCase(
                Select(['data', 'firstName'], Var('row'))
              ),
              2,
              3
            ),
            NGram(
              LowerCase(
                Select(['data', 'middleName'], Var('row'))
              ),
              2,
              3
            ),
            NGram(
              LowerCase(
                Select(['data', 'surname'], Var('row'))
              ),
              2,
              3
            )
          )
        )
      )
    }
  }
});

And when I run fauna-schema-migrate generate, it generates the following:

CreateIndex({
  name: "searchUsersByName",
  terms: [{
    binding: "search"
  }],
  source: {
    collection: Collection("users"),
    fields: {
      search: Query(Lambda(["row"], Union(Ngram(LowerCase(Select(["data", "firstName"], Var("row"))), 2, 3), Ngram(LowerCase(Select(["data", "middleName"], Var("row"))), 2, 3), Ngram(LowerCase(Select(["data", "surname"], Var("row"))), 2, 3))))
    }
  }
})

Notice that NGram has been transformed into Ngram which is now incorrect. when I ran the migration, I got the following error:

Fauna Schema Migrate - 2.1.0
---------------------------------------

--- Finished subtask Retrieved current migration state

Error in file: fauna/migrations/2021-05-02T03_43_07.746Z/create-index-searchUsersByName.fql
  Ngram is not defined

EDIT 1:

I tried manualy editing the generated migration to:

CreateIndex({
  name: "searchUsersByName",
  terms: [{
    binding: "search"
  }],
  source: {
    collection: Collection("users"),
    fields: {
      search: Query(Lambda(["row"], Union(NGram(LowerCase(Select(["data", "firstName"], Var("row"))), 2, 3), NGram(LowerCase(Select(["data", "middleName"], Var("row"))), 2, 3), NGram(LowerCase(Select(["data", "surname"], Var("row"))), 2, 3))))
    }
  }
})

I simply updated Ngram to NGram but got the same error with different trail.

I have updated to version 2.1.2 but still the same error as above.

Hi @aprilmintacpineda ,

Thanks for reporting this. It looks like you’ve also reported it on the GitHub repo and it’s generated an issue for the JavaScript driver. Please keep an eye on that issue for any updates.
