AFx Library library exception FOR R Modules

Hi,
I output a dataset from port1, input it to another R module Input port 1, but every time, it gives me:
requestId = 04c3444f096f4ff8b17edd1d055cfa4a errorComponent=Module. taskStatusCode=400. {"Exception":{"ErrorId":"LibraryException","ErrorCode":"1000","ExceptionType":"ModuleException","Message":"Error 1000: AFx Library library exception: Column names cannot be null or empty.","Exception":{"Library":"AFx Library","ErrorId":"EmptyColumnName","ErrorCode":"151","ExceptionType":"LibraryException","Message":"Column names cannot be null or empty."}}}Error: Error 1000: AFx Library library exception: Column names cannot be null or empty. Process exited with error code -2

I can not print anything in the second r module, what's wrong?

NAW.

@NAW123-0733 Error 1000 is an unhandled exception that occurred in your case because the data that is passed to one of your Execute R module does not have a column name or values which is referenced inside the module script. The best way to check what could be wrong is to visualize your dataset or data from any of the previous modules in your experiment and then use necessary data transformation modules like Edit Metadata or Clean missing data and remove the column or rows that do not contain values and then reference the data in the R script. I hope this helps!!

Clean missing data module should be the best bet to remove columns that are missing data. I would suggest checking the execute R script module that errors out and remove any column that it is referencing by connecting clean missing data between the two execute R script modules.

I added cleaning missing data module in between the rmodules, still the same error.
