使用大叶草绘制Choropleth贴图时发生TypeError

Question

我想在Choropleth地图上绘制2019年4月举行的印度的选举结果;当发生绘图错误时，我无法获取它。 发生错误的代码块：

<searchComponent name="suggest" class="solr.SuggestComponent">
    <lst name="suggester">
      <str name="name">mySuggester</str>
      <str name="lookupImpl">FuzzyLookupFactory</str>
      <str name="storeDir">suggester_fuzzy_dir</str>

      <str name="dictionaryImpl">DocumentDictionaryFactory</str>
      <str name="field">name</str>
      <str name="suggestAnalyzerFieldType">textSuggest</str>
      <str name="buildOnStartup">false</str>
      <str name="buildOnCommit">false</str>
   </lst>
</searchComponent>

geojson file dataframe named as election
