Support for eu-west-2 (London)?

[proffalken]

Hi all,

I'm currently getting the following stacktrace and I'm wondering if it's because I'm running this against London:

Is anyone able to provide advice on whether Simian Army runs against London yet?

Thanks,

Matt

Support for eu-west-2 was added in AWS Java SDK 1.11.70.

However, the project currently uses version 1.11.28:

https://github.com/Netflix/SimianArmy/blob/e2d95e581a8bd75faae81f166daa4297add747c5/build.gradle#L41

So fixing may be as easy as bumping that version.

Sadly, that's not it.

I've updated build.gradle to use both 1.11.82 and 1.11.107 and I get exactly the same result.

I'd love to move to the new Chaos Monkey, but as I don't run spinnaker, it's not really an option. :(

OK, fixed it, it was an issue with the formatting in the config file

If you put quotes around the "region" variable in client.properties, they are not removed when the endpoint is created.

If you remove the quotes it works fine.
