Call to undefined function Aws\default_http_handler()

[diggersworld]

Running into the following error when trying to work with AWS. If I instead use a local Elasticsearch connection everything works as expected.

I'm using elasticsearch/elasticsearch@v6.7.0 and cviebrock/laravel-elasticsearch@3.5.1. I've tried various other versions too but still hit the same issue.

I gather I need to install either of these packages: https://packagist.org/packages/aws/aws-sdk-php https://packagist.org/packages/cviebrock/laravel-elasticsearch?query=aws

I just updated the docs for this. Yes, you will need to do:

composer require aws/aws-sdk-php:^3.80
