Fatal error: Method Kirby\Editor\Blocks::__toString() must not throw an exception

1

ok… this seems to be a little bit complicated on read… the final problem is:
$item->text()->blocks() throws the error, when calling a site with a custom tag, which uses a custom snippet, that i made…

long story:
i could not upgrade to kirby 3.5 yet… but will in near future… (my used template gets an upgrade soon)

i am using kirby3-feed and kirby3-video with a custom snippet for videos (i need a player with captions and quality selector - in my case i use plyr.io):

since i’m not a real- but more a hobby-coder, this code is for sure not good code… but it worked. =)

now, when using kirby3-feed, to generate a RSS-Feed by parsing my journal entries, i get this error while trying to parse Block fields “$item->text()->blocks()” that include the kirbytag for the video (the tag calls the snippet above):

Just a friendly thread-push =)

fixed it by changing $kirby->url('assets') to kirby()->url('assets')
