mod_rest: Catch and log errors in callback promise chain From the code it looks like it should be possible to reply to an error stanza, but it did not. Turns out I was saved by my local developer mode module which throws errors if an attempt is made to create an errror reply to an error stanza. However nothing collects this error from the promise, so all I got was confusion.

# Introduction

This module adds support for reading AWS IAM access credentials from EC2 instance metadata,
to allow Prosody modules to gain role-based access to AWS services.

# Configuring

``` {.lua}
modules_enabled = {
    "aws_profile";
}
```

There is no other configuration.

# Usage in other modules

Other modules can import the credentials as a shared table:

``` {.lua}
local aws_credentials = module:shared("/*/aws_profile/credentials");
do_something(aws_credentials.access_key, aws_credentials.secret_key);
```

Note that credentials are time-limited, and will change periodically. The
shared table will automatically be updated. If you need to know when this
happens, you can also hook the `'aws_profile/credentials-refreshed'` event:

``` {.lua}
module:hook_global("aws_profile/credentials-refreshed", function (new_credentials)
  -- do something with new_credentials.access_key/secret_key
end);
```

# Compatibility

Meant for use with Prosody 0.11.x, may work in older versions.
