Problem with aliasing expression for "a depth-first" query using Esqueleto's "withRecursive"

Question

I'm trying to run the following query with a recursive common table expressions using Esqueleto's withRecursive but received an unexpected error at runtime.
Is there a way to fix this?

select $ do
        cte <- withRecursive
            (do
                  x <- from $ table @SignTag
                  where_ $ isNothing_ $ x ^. SignTagGroup
                  let level = val (0 :: Int)
                  return (level,x)
            )
            unionAll_
            (\parent -> do
                  (l,_) :& x <- from $ parent
                      `innerJoin` table @SignTag `on` (\((_, p) :& x) -> just (p ^. SignTagId) ==. x ^. SignTagGroup)
                  let level = l +. val 1
                  orderBy [desc level]
                  return (level,x)
            )
        from cte

Runtime error:

[Error#yesod-core] SQLite3 returned ErrorError while attempting to perform prepare "WITH RECURSIVE \"cte\" AS (SELECT ?

The generated query is:

  , "sign_tag"."id" AS "v2_id"
  , "sign_tag"."name" AS "v2_name"
  , "sign_tag"."descr" AS "v2_descr"

)
