Dear people of Netlify, hi!

First post after three years almost solving with the forum but this time I cannot deal with the error by myself alone.

I upgraded the hugo version from 0.74.3 to 0.101.0 because I was reporting an error with .Crop function whereas in my localhost with 0.101.0 everything was smooth.

From now on, the following error:

My netlify.toml:

[build]
command = "hugo --gc --minify"
publish = "public"

[context.production.environment]
HUGO_VERSION = "0.101.0"
HUGO_ENV = "production"
HUGO_ENABLEGITINFO = "true"

Any help, please?

Sounds like a Hugo issue, please refer to (and post): Hugo new ... complains about mkdir failing (0.97.3) - support - HUGO

The fact is - I can run my website smoothly localhost just executing hugo in the main directory of my project; once uploaded on netlify I got the error.

This suggests me Netlify may be the problem.

I tried also upgrading the version to the latest (0.110.0) but still the error remains.

I am losing the hope indeed :smiley:

Hi @parisi-n , it looks like you may have self-resolved this issue as I see the site is now up-and-running :partying_face: Let us know if that’s not the case!

I have “resolved” in a “non-way”: just downgraded the hugo version to the lowest not to generate the build error.

I hope it will be fixed somehow in the next future.

Thank you for your help :slight_smile:
