Same thing happened to me since v3.24

[DeepseaXX]

I don't know if it works for you, but after I tried to apply changes from this commit, and changed HUGO_VERSION: 0.123.8 in github\workflows\hugo.yml, it turns to work.

[CaiJimmy]

v0.123.8

This error should not appear if you are using Hugo version >= 0.123.0. Check the Hugo version you are using in CloudFlare Page building process.

[CaiJimmy]

I don't know if it works for you, but after I tried to apply changes from this commit, and changed HUGO_VERSION: 0.123.8 in github\workflows\hugo.yml, it turns to work.

By default, GitHub action pulls the latest version of Hugo. Fixing a specific version is not recommended to do.

[wagtale]

Thanks changing the hugo version to 0.123.0 made it work.

[lkaupp]

For cloudflare pages, just manually specify the HUGO_VERSION variable in your environments: 0.125.3
Current version number can be found here: https://community.chocolatey.org/packages/hugo
@CaiJimmy thanks for pointing this one out. It seems CFP uses an old outdated version of hugo out-of-the-box and you have to specify the new one if you want to get the latest version.

By default, GitHub action pulls the latest version of Hugo

I am sorry but the guide gives a fixed version: https://gohugo.io/hosting-and-deployment/hosting-on-github/#procedure at step 6.
