hiera hash to create_resources bombing - looking for how to troubleshoot

[Dan White]

I found this reported bug:
https://tickets.puppetlabs.com/browse/PUP-1100

Any clue how to debug it ?
This hit me when moving from Puppet 3.5.1 on RHEL 5 to Puppet 3.6.0 on RHEL 6
The defined type that it is barfing on is moderately complicated.

I've run into this a few times and I've found that looking at the server logs, or running the puppet master with --trace usually gives me enough information to work out where the error is being generated.

Creating a single instance of the defined type using the puppet syntax should help you see the errors.

Thanks, gentlemen, for the suggestions.

I will try both tomorrow.

For the single instance, should I do it explicitly in the dot-pp file or should I do it thru hiera ?  If I do not get a response in time, I will try both ways.

Looking forward to Puppet Camp in DC next week.

I would do it in a .pp file. Removing as many variables as possible is a good thing.

Found it !
A stray case change in an exec resource ( command --> Command )

Many thanks.

I created a puppet function to help with debugging things the contents of variables.  I am going to see if this can be added to std lib.  However for now, just put this in your module code under lib/puppet/parser/functions.  You will want to have at least one rspec unit test for speedy results, otherwise you will need to search a bunch of logs for the value during your puppet run.

I can't say enough how useful this is when used with a unit test (rspec-puppet)

usage:  dump_args($somevar1, $somevar2, $somevar3, ...)  (anywhere in your puppet code for debugging only)

I see that you already solved it, but keep this in mind for later as knowing which variables are not being populated correctly is extremely useful since variable contents are difficult to see.
