ERROR: can't modify frozen Chef::Node::ImmutableMash

Hi,

After some period where I did not update my server code, i'm facing the following error:

* apt_package[nodejs] action install (up to date)
Recipe: unicorn-ng::default

Chef: 13.7.16

unicorn-ng (2.0.1)

Any idea? Thanks. :)

The cookbook is currently not compatible with Chef 13.

Chef 13 doesn't allow the way I'm inferring defaults for resources from attributes - which is the only reliable way I found to make a cookbook compatible for use with node attributes as well as wrapper-cookbooks (using providers).

To upgrade this, it's probably necessary to drop attribute support completely (potentially breaking some setups) or rewriting the resource defaults using if statements and .dup.

Suggestions welcome!

Thanks to anwer @chr4 .

I tried with:

$ chef-solo -v
Chef: 12.21.31

Same error:

Sorry about my question, but I'm not used to use the resources and providers files. The problem comes from this files? Could we drop this files? Maybe just the templates and service commands could be a recipe.

[chr4]

This might also be because of chef-solo maybe?
I'm running this without problems with chef-12.19.36 - but this should obviously be ported to Chef-13 eventually. PR's welcome!

[wbotelhos]

I use knife-solo and I'm not tested without it.
For now, just copy um template file and config is enough.
Maybe with more time I try to understand better this problem.

Thank you.
