NoMethodError when parallel push of policyfile

[stonesbg]

Description

Trying to do parallel push of a single policyfile to multiple policy groups. This is being executed from a jenkins pipeline. I am guessing it is something to do with the lock file being accessed by more than once process at the same time.

ChefDK Version

I have tried this with 2.4.17 and 1.6.11

Platform Version

Windows Server 2012 R2

Replication Case

Create a batch file .bat or similar solution in order to create parallel exceution of the command chef push. I have been able to replicate this by having a bat file with start chef push ... with a total of 10 executions.

Stacktrace

Error: Invalid lockfile data
Reason: (NoMethodError) undefined method `[]' for nil:NilClass

@stonesbg Any chance you can try to reproduce this with the latest ChefDK. We'd made changes to policyfiles as well as bumped the Ruby version.

Is there any update on this? We also faced this on parallel push to multiple policy groups from jenkins pipeline.
