no implicit conversion of nil into String #182

Closed JustLeo closed 8 years ago

JustLeo commented 8 years ago

Hello, I'm getting the following message error:

TypeError

       no implicit conversion of nil into String
       Cookbook Trace:
       ---------------
       C:\Users\ADMINI~1\AppData\Local\Temp\kitchen\cookbooks\aws\providers\s3_file.rb:34:in 'do_s3_file'
       C:\Users\ADMINI~1\AppData\Local\Temp\kitchen\cookbooks\aws\providers\s3_file.rb:9:in 'block in class_from_file'

so my question is: what are these lines trying to do?

33: obj = ::Aws::S3::Object.new(bucket_name: new_resource.bucket, key: remote_path, client: s3) 34: s3url = obj.presigned_url(:get, expires_in: 300)

filename: s3_file.rb

I am facing the same problem. Any workarounds?

I have this issue as well, using log level debug I get

I'm on an EC2 instance with chef solo

$ chef -v
Chef Development Kit Version: 0.10.0
chef-client version: 12.5.1
berks version: 4.0.1
kitchen version: 1.4.2

Here is my recipe

aws_s3_file '/var/install' do
  bucket 'aws-codedeploy-us-east-1'
  remote_path 'latest/install'
end

I found the problem was the EC2 instance had failed to assume the iam role. Having a valid IAM role from the metadata service fixed it.

include_recipe 'aws'

Hey folks,

So the error 'no implicit conversion of nil into String' generally implies that something isn't getting defined that is required.

For S3 you need to have a recipe that looks somewhat like the example from the test cookbook: https://github.com/chef-cookbooks/aws/blob/master/test/fixtures/cookbooks/aws_test/recipes/s3_file.rb

i.e.:

aws_s3_file '/tmp/an_file' do bucket node['aws_test']['bucket'] remote_path node['aws_test']['s3key'] aws_access_key_id node['aws_test']['key_id'] aws_secret_access_key node['aws_test']['access_key'] end

This is also available in the README:

https://github.com/chef-cookbooks/aws/blob/master/README.md

It looks like maybe you aren't defining permissions in your recipe. Going to go ahead and close this. Please reopen if this doesn't fix your issue.

Thanks!
