I know this question was posted many times. but I have no clue how to find out solution. I am getting below error in agent.

(<unknown>): did not find expected key while parsing a block mapping
at line 5
    column 3

Below is my hiera.yaml file

  - yaml
  :datadir: /etc/puppet/hiera
  - '%{::env}/test/nodes'
  - '%{::env}/test/sudo'

I tried run with --trace but it is not giving much, printing same error.

What are you trying to do? A bit more info would be nice. Did you try using hiera from the command line to check if it ouputs the data you think it does? hiera -d (your key) environment=(your env).

There is a formatting problem in your yaml file(s). You can try using yaml-lint to find out where the problem is. You can install it with gem install yaml-lint, or use the following code snippet:

package { 'yaml-lint':
  ensure   => installed,
  provider => 'gem',

Then run yaml-lint on your hiera datadir: yaml-lint /etc/puppet/hiera.

Yaml-lint is not part of any defauly yum repository I know of. I have expanded my answer with a code snippet that installs yaml-lint for you

Thank you. I downloaded yaml-lint gem, it really reduced my formatting problem in yaml file.

In my case there was a formatting error in the yaml hiera file for the node. I had an extra quote mark within a password. I found this by opening the file in sublime the text was highlighted in white.
