Table to HTML : Configure failed (NullPointerException): null

Dear users,
I have tried to create an HTLM report by using the Table to HTLM node. I have around 2'600 rows with chemical structures but when I have finished the configuration procedure, this error pops up in the console :
ERROR     Table to HTML                      Configure failed (NullPointerException): null

Some rows were containing empty values, so I have added a Missing value node to replace empty rows.  
Is it related to the Knime Preferences (referring to other posts in the Forum) ?
By the way, I am able to create xls or SDF file...

Thank you for your help
