If you are getting a 'Problem Occurred Error: An internal error occurred during: "Load DataXXX"', resulting in a Null Pointer Exception when running Smart Loader via the Data Lab in Teradata Studio, there is a workaround. There are two options identified as workarounds. For both options, log in to the desired connection in the Data Source Explorer. Then navigate to desired Data Lab Database name and Tables folder. Make sure you are in the Data Transfer Perspective (tab at the top of the window).
From here, you have two options:
Option 1: Go to Data Lab View tab, and run Smart Loader, as before.
Option 2: Run the “Smart Loader” from the Data Source Explorer. The steps for this are:
From Tables folder, right click and select “Teradata> Data Transfer….” menu option. Then change the Source Type to External File (Smart Load). Click Launch to launch the Smart Loader Wizard.
Update: We have released version 15.00.02.00 of Studio, Studio Express, and Teradata Plug-in for Eclipse that have the fix for this problem. Please visit the Developer Exchange Download page for the latest releases.
