Re: update_policy.cf fails in 3.18.1

Thanks, Nick.  There still seems to be a gap in my understanding.

Here's where the update bundle is specified:

root@butcher1 [cfengine]# cf-promises -f ./inputs/update.cf 
--show-vars=default.def.mpf_update_policy_bundle
Variable name                            Variable value                     
                          Meta tags                                Comment 
                                
default:def.mpf_update_policy_bundle     update_templates                   
                          source=augments_file

Hers's where the input containing the update bundle is defined:

root@butcher1 [cfengine]# cf-promises -f ./inputs/update.cf 
--show-vars=default.def.update_inputs
Variable name                            Variable value                     
                          Meta tags                                Comment 
                                
default:def.update_inputs                 
{"/var/cfengine/inputs/update_templates.cf"}               
 source=augments_file

Here's the input file:

root@butcher1 [cfengine]# grep bundle inputs/update_templates.cf 
bundle agent update_templates { 

So what am I missing?
