Error using LookupTableReaderWriter

Hi there,

I created a clover project(version 3.2.1) as attached to use the component LookupTableReaderWriter.
Why the first pipeline in debug_graph.grf runs into the below errror:

ERROR [WatchDog] - Graph execution finished with error
ERROR [WatchDog] - Node LOOKUP_TABLE_READER_WRITER2 finished with status: ERROR caused by: null
ERROR [WatchDog] - Node LOOKUP_TABLE_READER_WRITER2 error details:

Could you please take a look at the attachment and shed some light on me?

Thanks,
