Files not uploading to S3

[seunex]

Hi,
I downloaded version 1.1.0 and installed.
The installation was successful, I configure the Constants as specified.
I have been trying to upload image with media or upload new plugins, None of these files gets Uploaded to S3.

instead of showing thumbnail on Media Upload, I get this error :

The uploaded file could not be moved to uploads. "path/name_of_file/"

Thanks in advance.

This error means that move_uploaded_file() failed when it was called inside _wp_handle_upload() in WP core.

What are your constants set to? Is S3 Uploads actually active?

Hello ,
Thanks for your response.

S3 Uploads is active Because when i deactivated it, the image upload to the wordpress uploads folder.

Also by constant, I'm sure you are referring to this.

define( 'S3_UPLOADS_BUCKET', 'myBucketName' );
define( 'S3_UPLOADS_KEY', '' ); //SET TO i am user key
define( 'S3_UPLOADS_SECRET', '' ); //set to i am user SECRET
define( 'S3_UPLOADS_REGION', ' ); //same as the location used in my bucket name.

What could be wrong please.

Thanks in advance.

I'm seeing similar behaviour, although not the error message. It looks like the wp_handle_sideload_prefilter action is never being called.

@rmccue There's no call to move_uploaded_file in 1.1.0, only in the 2.x betas.

@peterjanes Not sure what you mean by that; the call to move_uploaded_file is inside WordPress core's _wp_handle_upload(), not in S3 Uploads.

You should check that S3 Uploads is actually functionally active; there are a number of checks that will cause it to fail.

[peterjanes]

Understood. I thought your earlier comment was saying there was a call to the method in the plugin.

I added error_log statements around all of the checks I could find, and they all passed. I couldn't get the sideload action to be triggered at all, including in the beta from last year, so I've decided to use another plugin.

@rmccue where is this 'S3_UPLOADS_USE_INSTANCE_PROFILE' being generated? is not specifid in the docs

[rmccue]

@theasteve You're right, it's not documented, apologies.

tl;dr: rather than defining S3_UPLOADS_KEY and S3_UPLOADS_SECRET, you can define S3_UPLOADS_USE_INSTANCE_PROFILE. This will tell the AWS SDK to use the default credentials which are:

1. Load credentials from environment variables.
2. Load credentials from a credentials .ini file.
3. Load credentials from an IAM role.

Hi, I tried all variations, S3_UPLOADS_KEY, S3_UPLOADS_SECRET and S3_UPLOADS_USE_INSTANCE_PROFILE on a fresh install of wordpress V5.2.1 php7.3, site keeps crashing with following error.

The site is experiencing technical difficulties. Please check your site admin email inbox for instructions.

In the email sent;
Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

In this case, WordPress caught an error with one of your plugins, S3 Uploads.

Not sure what to try next
