I have a problem concerning XML data with empty rows (from Matomo - web analytics on a daily basis with occasional days without any users).
What I'd basically like to do is to use the Select all <field name> elements in all <parent> elements, adding blanks for missing <field name> elements selection option (as shown on https://support.klipfolio.com/hc/en-us/articles/215547118-About-JSON-and-XML-Data-Sources).
However this option is not displayed. I only have six options and adding blanks is none of them.
When I try to use @kf:fill_elements operator manually, an error occurs: There was an error fetching the results for the model.
Is there a general answer for reduced selection options in XML data?
Thanks in advance!
