no implicit conversion of nil into String on knife google server create

[ChadScott]

I've noticed that knife google server create successfully creates the disk, as I see it in the console, but apparently bombs out somewhere between that and launching the VM itself.

[ChadScott]

@start_time = Time.parse( data["startTime"] ) appears to be the culprit but I haven't had time to dig deeper. I'm guessing data["startTime"] is nil.

Thanks for digging into this. I'll make some time on Monday to take a look
too.

Alright, I'm at a loss. I've dug on this for a little bit and I don't know enough about the GCE API nor the internals of Knife to really be able to get to the bottom of it without going into a cave for awhile. Any luck on your end, @paulrossman?

[ChadScott]

If it helps, here are the versions of the Google related gems:

google-api (0.4.0)
google-api-client (0.7.1)
googleauth (0.4.0)
knife-google (1.3.1)

[paulrossman]

Sorry for the late reply. I've not run in to this issue at all and have been building lots of instances recently.

My suggestion is to update to knife-google 1.4.x. There were a bunch of gemspec changes in #54. I currently have these gem versions installed:

chef (12.2.1)
google-api-client (0.8.5)
googleauth (0.4.0)
knife-google (1.4.3 5a4ccf4)

[ChadScott]

After upgrading to knife-google 1.4.3 (which isn't in the gem repo, by the way... I had to pull it down from Github and manually install it), I get yet another error:

knife google zone list
ERROR: Faraday::SSLError: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

I thought at first it must be something in my SSL stack, but it works fine for ec2:

knife ec2 flavor list --aws-credential-file .boto
ID                                       Name                                     Architecture                             RAM                                      Disk  Cores
c1.medium                                High-CPU Medium                          32-bit                                   1740.8                                   350 GB                                   5

...etc

[ChadScott]

Okay, I finally figured this out. For those that find this via googling or whatever, this is a problem with chefdk on MacOS. I'm unsure exactly what the issue is, but this solves it for me:

Install brew (brew.sh)
brew install ruby
gem install chef
::download knife-google from this repo::
rake
gem install pkg/knife-google-1.4.3.gem
knife google zone list

Voila!

[jameshcoppens]

I am still getting this error as well. I'm not really interested in building my own gem. I'll see if I can resolve for knife-google 1.3.1

[jameshcoppens]

So, I figured out the issue with a small code change.

Chad, you were absolutely right. The code line

@start_time = Time.parse( data["startTime"] )

was the culprit.

The reason why when you build the 1.4.3 gem it works is in that version there is a null check on the variable. I think that the new gem version should be built and distributed. I simply changed the following lines in my lib/google/compute/zone_operation.rb file

@insert_time = Time.parse( data["insertTime"] ) if data.key?("insertTime")
@start_time = Time.parse( data["startTime"] ) if data.key?("startTime")

[ohadperry]

I have tried that in both global_operation.rb and zone_operation.rb and it doesn't seem to work.
Is there a way to run this with a stack trace?
tried:
knife google --verbose zone list

[ohadperry]

Is there another gem that does that?

[jameshcoppens]

ohadpartuck,

I've used -VV on the end of the string. Can you output what you see when you run the command. This plugin is really important especially if you are negotiating with Amazon about your monthly AWS bill.

knige google zone list -VV

[ohadperry]

@jeremiahsnapp ok , that helped , After 15 mins, I tracked the issue to
signet-0.7.0/lib/signet/oauth_2/client.rb:1182 -> normalize_timestamp
it reading "2015-12-16 17:20:39 +0200" from my oauth file .google-compute.json
and doing
Time.parse("2015-12-16 17:20:39 +0200")
It failed for no implicit conversion of Time into String (TypeError)

weirdly, I ran it in the console and it works:

2.1.5 :005 > Time.parse("2015-12-16 17:20:39 +0200")
 => 2015-12-16 17:20:39 +0200

Now that I see that, it's not the same error as stated in this log.

any ideas?

[ohadperry]

@sqrrrl maybe you can take a look?

[sqrrrl]

Argh. Yes, there was a stupid bug introduced in 0.7. Just pushed 0.7.1 which should fix the issue.

@ohadpartuck - Please update and let me know if it addresses the issue you're seeing.

[ohadperry]

@sqrrrl I don't see 0.7.1 neither here
https://rubygems.org/gems/signet/versions/0.7.0
or here
https://github.com/google/signet/releases
can you send a link

[ohadperry]

nvm , found it here
https://rubygems.org/gems/signet/versions/0.7.1
