Error: Key must be a buffer TypeError: Key must be a buffer about aws-es-curl HOT 4 CLOSED

Hello @snakelab,
as far as I know, this issue can be caused by two main reasons. See below:

1. If you are not using profiles (see README.md), it means that you don't have the environment variables AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY configured on the shell where you are executing the aws-es-curl command.

   To check this, use something like printenv and see if they appear on the output. If they don't, just export them using the following commands:

   export AWS_ACCESS_KEY_ID=<YOUR AWS KEY ID>
export AWS_SECRET_ACCESS_KEY=<YOUR AWS SECRET ACCESS KEY>

2. If you are using profiles, it looks like you have something wrong on the profile configuration you are using.

Thanks,

It looks like this can be worked around by 1. merging your config into your credentials file, e.g.

$ cat ~/.aws/credentials
[default]
aws_access_key_id = ABCDEF...
aws_secret_access_key = s3krit...

[foo]
region = us-west-2
role_arn = arn:aws:iam::0123456789012:role/my-role
source_profile = default

and 2. inserting this code on line 36 of index.js:

  return credentials.getPromise();

I'll create a PR for the latter.

Unfortunately this can also happen if you use profiles that don't have their own credentials but instead assume a role, e.g.

$ cat ~/.aws/credentials
[default]
aws_access_key_id = ABCDEF...
aws_secret_access_key = s3krit...

$ cat ~/.aws/config
[profile default]
region = us-west-2

[profile foo]
region = us-west-2
role_arn = arn:aws:iam::0123456789012:role/my-role
source_profile = default

aws-es-curl doesn't currently supports this scenario, as there is no logic to generate and use AWS.TemporaryCredentials

@jenseng thank you for contributing! this fix is included in v1.0.8
