Undefined method to i for chef node ImmutableArray


When bootstrapping a node that is running Centos7 I am given this error

ERROR: undefined method `to_i' for ["300"]:Chef::Node::ImmutableArray

Here is the section of code it points me to:

default['chef_client']['task']['frequency_modifier'] = node['chef_client']['interval'].to_i / 60

This is in the chef-client cookbook pulled from the supermarket. I haven’t edited anything within the cookbook directly, only through an environment to change the interval to 300.

Any help would be appreciated!

Ah disregard, I found the error in the unnecessary square brackets around the “300”
