fatal error: systemstack called from unexpected goroutine about terragrunt

[brikis98]

Hm, strange. Please post the stack trace when you have it so we can track this down!

Added link to stack trace to description

Wow, bizarre. If I'm reading your stacktrace correctly, it points to this line in dynamo_lock_item.go:

output, err := stsconn.GetCallerIdentity(&sts.GetCallerIdentityInput{})

Browsing the stacktrace, it looks like a potential bug in the AWS Go SDK or even the underlying Go HTTP libraries it's using to make API calls.

New day, new crash log. Maybe you will see anything strange in that one. Rerun works fine.

I independently verified it's the same GetCallerIdentity() function that caused the panic and it seems to be happening when the HTTP request itself is sent, so I'm in agreement with Jim that this is most likely an issue witht he AWS Go SDK.

That being said, I notice that we are on a relatively old release of the AWS SDK, so I'll update to the latest commit and issue a new release. Once that happens, can you let us know if this happens again?

Thanks for reporting this!

[antonbabenko]

@josh-padnick I will be glad to try it out and report as soon as I hit it again.

@antonbabenko I just released a new version of terragrunt with all dependencies updated: https://github.com/gruntwork-io/terragrunt/releases/tag/v0.1.1. It'll take a few minutes for the build to run, after which new binaries should show up in that release. Please give them a shot when you have a chance and let us know if you're still seeing this bug. Thanks!

Sorry about that, looks like GitHub was briefly down. I just reran the build and it passed: https://github.com/gruntwork-io/terragrunt/releases/tag/v0.1.1

[antonbabenko]

Thanks guys. I have installed it and will be using it. Closing this issue now, will open new issue if problem persists.
