Start with the stack trace in plugin/writer/tdenginewriter/DefaultDataHandler.java, especially indexOf at line 552 and writeBatchToSupTableBySchemaless at line 317. Compare the reader and writer column lists in the supplied DataX configuration, then reproduce the td-to-td sync; done means the reported column lookup failure is explained and the configuration or handling has a verified resolution.
