When using the websearcher node I am often encountering error messages that tell me
Execute failed: ("NullPointerException"):null
Not being a java wizard, I don't understand what is going wrong....my input cells are all simple text (string), search is set to Google, returning 5 results in English. The error message is a bit hit or miss which makes it all the more infuriating.
So, as an example I have a "Row Sampling" node immediately before the WebSearcher, and the WebSearcher was successful for 1,2,3, and 5 rows sampled from the top, but then failed with 10 rows. Cutting this back to 5 rows then led to an error, whereas just before it had worked! Deleting and replacing the node then failed again.
Anyone have any pointers as to potential issues?
