'eq' not found

[FuzzLightyear]

I have the blueprints defined, but get the following error on trying to repeatedly calling Services.make! ie 50.times { Services.make! }

The blueprint:

# machinist blueprint definition for the object
  Services.blueprint do
    portID              { randomize_foreign_key("ports") }       # Link to portID foreign_key
    protocol            { get_protocol() }                     # Random service name - need better seeds
    product             { (["MS Active Directory","Kerberos","MySQL"].shuffle)[1] }                # unsure about this
    version             { rand(9).to_s + "." + rand(9).to_s }                  # random version number definition
    extraInfo           { Faker::Lorem.sentence(rand(15)) }      # randomized text Lorem
    timestamp           { Time.now() }                           # Current timestamp inserted
  end

The error

undefined method `eq' for nil:NilClass

Would appreciate any help on this.

The first make! call seems to execute and populate my database but on consecutive calls in the loop it falls with the above error.

I seem to be getting this on all blueprints.

Currently I'm suppressing the 'no method' errors just to have it execute without breaking my loops, but would be nice to understand and be able to fix this.
