@medyagh It looks like the Netlify build image currently in use may be outdated, which can cause compatibility issues with newer Hugo versions.
You can update it by selecting a newer image here:
https://app.netlify.com/projects/kubernetes-sigs-minikube/configuration/deploys#build-image-selection

More details on build image options are available in the Netlify docs:
