Error while doing "sudo puppet agent --test" in puppet slave

Question

 I am doing "sudo puppet agent --test" in puppet slave, I am getting below error.

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: A substring operation does not accept a String as a character index.

class java {
 

 exec { "Test for Java":
  command => '/bin/echo java is not installed > /tmp/java_notinstall.txt',
  unless => '/bin/which java',
  

}
 

   package { 'openjdk-8-jre-headless':                                  
   ensure => installed,
   require => exec['Test for Java'], 
   
   }
  }

Please help me to solve this issue.

Answer 1

The error had happened as you've specified the exec in lowercase in Line 60 and column 20. Change the exec from lower case to upper case.

So, basically your line 60 should be like:

   require => Exec['Test for Java'], 

Refer to the screenshot attached.
