tidyfeed error in tibble: columns must have compatible sizes

[jzadra]

For this feed: independent.com/feed, I get the following error from tidyfeed():

Error in `tibble()`:
! Tibble columns must have compatible sizes.
• Size 10: Existing data.
• Size 9: Column `item_guid`.
ℹ Only values of size one are recycled.

It looks to me like one of the items doesn't have a parameter set for item_guid. Perhaps rss_parse() could handle an empty column and fill it with NA? It looks like there is lots of logic in the entries <- ... code to fill default values with def (NA_character_), but for some reason it isn't handling item_guid.
