Hi,

I am new to CloverETL. I am using Version: 3.3.0.063M1.

I am trying to fetch data from 2 database tables and put data into new table.

When I try view data, I get - “Failed to initialize edge debugger: Temp file does not exist.” error.

I see following error when I run the graph.

INFO [main] - Graph definition file: graph/firstgraph.grf  
ERROR [main] - Can’t create object of : CLOVER\_WRITER exception: java.lang.NullPointerException  
CLOVER\_WRITER:CLOVER\_WRITER0:Attribute/property not found: fileURL

Can you please help me out.

Thanks
