Erlang 为什么这个列表显示为空，但元组可以很好地解析？

我正在将一个充满erlang对象的元组转换为映射，我计划稍后将其转换为JSON

正在使用2元素元组调用tileJSON函数。我希望在每个tableCache元素的映射中看到一个包含平铺的行列表。相反，我看到的是：

#{"availableTablePids" => ["<0.477.0>"],
  "hall" => [],
  "tableCache" => [],
  "tablePids" => ["<0.477.0>"]}

我得到以下数据：

#{"availableTablePids" => ["<0.477.0>"],
  "hall" => [],
  "tableCache" => [#{"actions" => #{"current" => "x","o" => #{"next" => 0,"now" => 0},"x" => #{"next" => 0,"now" => 2}},
     "board" => [[{"spawn","x"},
       {"empty","null"},
       {"empty","null"},
       {"empty","null"},
       {"empty","null"}],
      [{"empty","null"},
       {"empty","null"},
       {"empty","null"},
       {"ridge","null"},
       {"empty","null"}],
      [{"empty","null"},
       {"empty","null"},
       {"ridge","null"},
       {"empty","null"},
       {"empty","null"}],
      [{"empty","null"},
       {"ridge","null"},
       {"empty","null"},
       {"empty","null"},
       {"empty","null"}],
      [{"empty","null"},
       {"empty","null"},
       {"empty","null"},
       {"empty","null"},
       {"spawn","o"}]],
     "clock" => #{"current" => "x","o" => 3000,"status" => "unstarted","x" => 3000}}],
  "tablePids" => ["<0.477.0>"]}

atomJSON(Atom) -> atom_to_list(Atom).

tileJSON({Status, Sitter}) ->
  [atomJSON(Status), atomJSON(Sitter)].

rowJSON(Row) ->
  lists:map(fun(Tile) -> tileJSON(Tile) end, Row).

boardJSON(Board) ->
  lists:map(fun(Row) -> rowJSON(Row) end, Board).

tableCacheJSON(Cache) ->
  lists:map(fun(#{actions := Actions, clock := Clock, board := Board}) -> 
    #{"actions" => actionsJSON(Actions),
      "clock" => clockJSON(Clock),
      "board" => boardJSON(Board)
      }
   end, Cache).

#{“availableTablePids”=>[“”]，
“大厅”=>[]，
“tableCache”=>，
“board”=>[[{“spawn”，“x”}，
{“空”、“空”}，
{“空”、“空”}，
{“空”、“空”}，
{“空”、“空”}]，
[{“空”、“空”}，
{“空”、“空”}，
{“空”、“空”}，
{“ridge”，“null”}，
{“空”、“空”}]，
[{“空”、“空”}，

{“spawn”，“o”}]]，
“时钟”=>{“当前”=>“x”，“o”=>3000，“状态”=>“未启动”，“x”=>3000}]，
“tablePids”=>[“”]}
atomJSON（原子）->原子到列表（原子）。
tileJSON（{Status，Sitter}）->
[阿托姆森（地位），阿托姆森（坐席）]。
rowJSON（行）->
列表：地图（乐趣（平铺）->平铺（平铺）结束，行）。
董事会（董事会）->
列表：映射（乐趣（行）->rowJSON（行）结束，板）。
tableCacheJSON（缓存）->
列表：地图（乐趣（#{actions:=actions，clock:=clock，board:=board}）->
#{“动作”=>actionsJSON（动作），
“时钟”=>clockJSON（时钟），
“板”=>boardJSON（板）
}
结束，缓存）。

程序没有崩溃。我原来的tileJSON函数有什么问题？

很抱歉，无法使用您显示的代码进行复制。与编辑器中的代码相比，您可能对当前编译和加载的代码感到困惑。但是，如果您仍然认为有问题，请尝试重新创建失败的情况，并发布导致错误的确切代码
