split and index

Question

I get the following error expression evaluation error at function 'split' [line 2]: A null parameter has been passed as parameter 1. 
 local!docOCR: split( index( rule!DMX_ScanImagenes(idDocumento: ri!idDocumento).result.responses.textAnnotations.description, 1 ), char(10) ), 
 how to solve it?

You will want to utilize a null check as split() will fail over null values, as you have noticed. Something like: 
 local!docs: rule!DMX_ScanImagenes(idDocumento: ri!idDocumento).result.responses.textAnnotations.description,
local!docOCR: if(
 isnull(local!docs),
 null,
 split(
 index(
 local!docs,
 1
 ),
 char(10)
 )
), 
 Also please check out the Insert -> Code feature when posting SAIL snippets, much cleaner :)
