i have tried looking on existing answers similar questions they've identified different problems don't seem reflect happening in case.

does have suggestions?

the problem .each on has return |key, value|. grabbing key string. call string['something'] expects index on string.

if change line 29 read:

<% node['cloudwatch-cookbook']['cwlogs']['logfiles'].values |group| -%> 

you should go.
