When I created this entry using a hugo command, I found these warnings:
WARN deprecated: project config key languageCode was deprecated in Hugo v0.158.0 and will be removed in a future release. Use locale instead.
WARN deprecated: project config key languages.en.languageName was deprecated in Hugo v0.158.0 and will be removed in a future release. Use languages.e
n.label instead.
WARN deprecated: project config key languages.es.languageName was deprecated in Hugo v0.158.0 and will be removed in a future release. Use languages.e
s.label instead
And to be completely honest with you, something in my mind asked me to copy the text to an AI and wait for a solution. In fact, I did it. But in the process of waiting for the answer I immediately realized how lazy I’m becoming. I went back to my terminal and I took the time to read line by line. And boom, nothing serious. I only had to replace some deprecated keys.
