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 :)
thank you I will check what you tell me
