Help how to use “variableType” in resultMap

run error:
org.flowable.variable.service.impl.db.IbatisVariableTypeHandler.()

A type handler is registered on the Mybatis configuration like

configuration.getTypeHandlerRegistry().register(VariableType.class, JdbcType.VARCHAR, new IbatisVariableTypeHandler(variableTypes));

This is already done in the engine configuration. What’s the use case you’re trying to solve?
