Hi All,

I have a number of cookbooks that install packages. Today for some reason the functionality has completely stopped working. The error I’m getting is as follows:

undefined method `declared\_key’ for Chef::Resource::YumPackage

Has anybody seen this before? Suggestions on how to go about fixing it?

Cheers,  
Josh

Hi,  
Which version of chef are you using, do you have the compat resource cookbok and if so which version, and please show the complete backtrace.  
Thanks,

I am seeing a similar issue, but with RubyBlock. The ruby\_block resource actually executes fine, but the Chef run fails.

Here’s the ruby\_block that sends the notification:

```
ruby_block "run_block" do
    block do
        Chef::Log.info("Sending notification")
        Chef::Log.info("Response in message: #{node['aws']['lambda']['sample_function']['resp_json'][this_env]}")
        notifies :create, "ruby_block[deploy_sample_lambda_function]", :immediately
    end
end

```

Versions:

```
/opt/chefdk/embedded/bin/ruby --version
ruby 2.1.8p440 (2015-12-16 revision 53160) [x86_64-darwin13.0]

The error:

```

Can we see your `ruby_block[deploy_sample_lambda_function]` resource?

Absolutely, here it goes:

Oh I think the problem is that `notifies :create, "ruby_block[deploy_sample_lambda_function]", :immediately` is inside of your code `block` property. `notifies` is a resource property but in the `block` you are running it as free ruby code.

It should look like:

```auto
ruby_block "run_block" do
    block do
        Chef::Log.info("Sending notification")
        Chef::Log.info("Response in message: #{node['aws']['lambda']['sample_function']['resp_json'][this_env]}")
    end
    notifies :create, "ruby_block[deploy_sample_lambda_function]", :immediately
end

```

That all said, I’m not sure what use you are getting out of this ruby block.

[SOLVED]  
Thank you gentlemen 🙂  
Moving the notification out of the block did the trick and now Chef finishes its run without issues.  
Again, many thanks!
