Exception thrown when trying to retrieve assets from prefix in S3 bucket

[AndrewReid-Journey]

I'm working on a site which uses S3 as its asset storage and for the most part this works fine. I wanted to move the items out of the bucket root and move them into a prefix inside the bucket, however after copying the files to a prefix of 'myprefix' and updating the .env value to include this, the Statamic site throws the following exception when navigating to it.

The .env values look like this :

AWS_DEFAULT_REGION="eu-west-1"
AWS_BUCKET="testbucket-alpha/myprefix"
AWS_URL="https://testbucket-alpha.s3.eu-west-1.amazonaws.com/myprefix"
AWS_ENDPOINT="https://s3.eu-west-1.amazonaws.com"
AWS_USE_PATH_STYLE_ENDPOINT=true

I noticed in the exception as part of the GET url, there is a prefix argument that is blank which I imagine is part of the problem here. If that is the case, how can I get that prefix argument to update?

Try removing the /myprefix part of the AWS_URL.

Instead, in your config/filesystems.php file for the S3 disk, add the root option:

'root' => 'myprefix',

Amazing, thank you for that. I had to also remove the prefix from the AWS_BUCKET but works like a charm. Thanks again.
