Nil pointer evaluating resource.Resource.Resize in version 0.57.0

Hi thank you for your answer.
I read this part in the release note but to be honest I didn’t understand everything I’m not a dev and English is not my native language, sorry for that i try to do my best.

the line 22 is the second :

{{ $cover := $images.Resize "600x q95 lancoz" }}

i guess this line is in error because the line before can’t get an image ( nil )
