Client credentials not retrived when attempting to use aws php sdk - php

Question

I am attempting to connect to a DynamoDB hosted on aws using php.
I am currently getting the following error:
Fatal error: Uncaught exception 'Aws\Exception\CredentialsException'
with message 'Error retrieving credentials from the instance profile
metadata server. (cURL error 28: Connection timed out after 1000
milliseconds (see
http://curl.haxx.se/libcurl/c/libcurl-errors.html))' in
C:\wamp\www\Aws\Credentials\InstanceProfileProvider.php on line 79
I've taken this to mean there are issues with my client credentials which I need to use the sdk. My credentials are coded as follows:
$client = new DynamoDbClient([
'profile' => 'my profile',
'region' => 'us-west-2',
'version' => 'latest',
'credentials' => [
'key' => 'my key',
'secret' => 'my secret key',
]
]);
From what I've seen this error usually means there is a problem with the way the credentials are formatted, but as far as I can tell I don't have that issue. I'm currently trying to run this program locally using wamp. I'm not sure what the problem is.

Please try below steps and check if it work correctly :
1) Download aws php sdk here.

try
{
$aws = DynamoDbClient::factory(array(
'key' => $aws_key,
'secret' => $aws_access_key,
