Gremlin MergeV创建顶点正常但更新时属性错乱求助

测试mergeV查询逻辑：顶点ID不存在则创建带属性的顶点，存在则更新对应属性。清空所有顶点后首次运行可成功创建3个属性正确的顶点，但再次运行修改了v-2的email值（改为person-22@example.org）的相同查询时，出现属性错乱异常：返回结果中v-1的email变成了person-22@example.org，v-2和v-3的email均为person-3@example.org。

相关查询语句 #

g.mergeV([(T.id):'v-1']).
    option(onCreate, [(T.label): 'Person', 'email': 'person-1@example.org', 'age': {age}]).option(onMatch, sideEffect(property(single, 'email', 'person-1@example.org')).sideEffect(property(single, 'age', {age})).constant([:])).
  mergeV([(T.id):'v-2']).
    option(onCreate, [(T.label): 'Person', 'email': 'person-22@example.org', 'age': {age}]).option(onMatch, sideEffect(property(single, 'email', 'person-22@example.org')).sideEffect(property(single, 'age', {age})).constant([:])).
  mergeV([(T.id):'v-3']).
    option(onCreate, [(T.label): 'Person', 'email': 'person-3@example.org', 'age': {age}]).option(onMatch, sideEffect(property(single, 'email', 'person-3@example.org')).sideEffect(property(single, 'age', {age})).constant([:])).
    id()

异常返回结果 #
