After I moved my project from Mendix 8.12.7 to 9.8.1, the excel importer templates where I have used the parsing method to import the data. I have updated the ExcelImporter module as well, still it doesn’t work. The error that’s getting showed is ”Error in monitored action ‘{‘’name’’:’’ExcelImporter.IVK_ImportTemplateDocument’’.’’type’’:’’Microflow’’}’ The detailed log message is as follows java.lang.NoSuchMethodError: com.mendix.core.Core.execute(Lcom/mendix/systemwideinterfaces/core/IContext;Ljava/lang/String;Ljava/util/Map;)Ljava/lang/Object;
