BackWPup extension error selecting S3 buckets

ten9its · February 6, 2020, 5:36pm

I use BackWPup and the MainWP extension to manage all my child site backups. I also have BackWPup installed on my dashboard site and it is set up as a child site so I can back it up along with everything else.

Since version 4.0, there is an issue with the BackWPup extension. After entering the Access and Secret keys, the error below shows up and I’m unable to select a bucket.

Before I noticed the error, I made a change to another setting and saved the job out to all child sites, which ended up disconnecting with S3 because no bucket was selected. I had to spend a day and a half going to each individual child site to reselect the S3 bucket and save the settings for each backup job.

The BackWPup plugin works fine on each child site - there is no error if I enter the S3 keys and select a bucket. I don’t know if it’s an issue with having the main BackWPup plugin installed on the dashboard site in addition the MainWP extension of BackWPup, but this really needs to be sorted out because I can’t add a new child site and sync backup jobs otherwise, I’ll have to spend another day and a half manually fixing each site’s jobs.

Is anyone else experiencing this issue?

BEGIN ERROR MESSAGE

Missing required client configuration options: version: (string) A “version” configuration value is required. Specifying a version constraint ensures that your code will not be affected by a breaking change made to the service. For example, when using Amazon S3, you can lock your API version to “2006-03-01”. Your build of the SDK has the following version(s) of “s3”: * “2006-03-01” You may provide “latest” to the “version” configuration value to utilize the most recent available API version that your client’s API provider can find. Note: Using ‘latest’ in a production application is not recommended. A list of available API versions can be found on each client’s API documentation page: AWS SDK for PHP 3.x. If you are unable to load a specific API version, then you may need to update your copy of the SDK.

END ERROR MESSAGE

Some additional information:

I deactivated the BackWPup plugin on my dashboard site to see if it is conflicting with the MainWP extension. While the error message is gone, I still can’t select a bucket; the dropdown list doesn’t respond to clicks. I can see in the code that my buckets are listed as options, but I’m unable to select one.

Seems like an error with the BackWPup extension. If anyone has any ideas, I’d appreciate the help.

I am having the same issue. I took a quick look at it and at least for me the issue appears to be a problem with the binding of the buckets to the Angular dropdown. The buckets are getting populated in the SELECT element, but not getting rendered in the Angular dropdown. As a quick fix I removed the bucket data binding and just hard-coded the bucket I wanted to use into the SELECT element. This is obviously a quick fix until this can be addressed in the plugin.

SAMPLE CODE MODIFICATION:
File: MainWPBackupDestinationS3.job.php
Line: 90

<!--
<select class="ui dropdown ng-binding" ng-if="scope_s3_buckets" name="s3bucket" id="s3bucket"
        ng-init="scope_s3_bucket='<?php echo esc_attr( MainWPBackWPUpView::get_value( $default, 's3bucket', '' ) ); ?>'">
  <option ng-selected="scope_s3_bucket==bucket" value="{{ bucket }}"
          ng-repeat="bucket in scope_s3_buckets">{{ bucket }}
  </option>
</select>
-->
<select name="s3bucket" id="s3bucket" class="ui dropdown">
  <option value="my-s3-bucket-name" SELECTED>my-s3-bucket-name</option>							
</select>

EDIT: I forgot I had removed the data binding class ng-binding from the original code block during my testing - I re-added it into my code sample.

Thank yo all for the update.

I notified the dev team about this problem. As soon as I get an update, I will let you know.

kensatx · February 7, 2020, 6:56pm

I have more info on this one. After I got the bucket configured I started to get the same error @ten9its was getting about the version not being set. When getting this error the S3 client construction fails so no buckets are returned. I looked into it and my guess is that the AWS SDK in the extension was updated from version 2 to 3. This means a couple changes need to be made to the S3 client configuration. I made the following modification and it is now working for me. Hope this helps.

FILE: MainWPBackWPupExtension.class.php
LINE: 557

/*
$s3 = Aws\S3\S3Client::factory( array(
  'key'      => $s3accesskey,
  'secret'   => $s3secretkey,
  'region'   => $s3region,
  'base_url' => mainwp_backwpup_get_s3_base_url( $s3region, $s3base_url ),
  'scheme'   => 'https'
) );
*/
$s3 = Aws\S3\S3Client::factory( array(
  'region'   => $s3region,
  'base_url' => mainwp_backwpup_get_s3_base_url( $s3region, $s3base_url ),
  'scheme'   => 'https',
  'version'  => '2006-03-01',
  'credentials' => array(
    'key'  => $s3accesskey,
    'secret'  => $s3secretkey
  )
) );

@kensatx thank you, the combination of both band-aids did the trick for the time being. I had already tried adding the version to MainWPBackWPupExtension.class.php but didn’t change it to use the ‘credentials’ parameter.

bogdan · February 10, 2020, 11:40am

Hi all, I just want to say thanks for helping out. I have sent the details to the dev team.

EricJacksch · February 23, 2020, 5:17pm

@kensatx Thank you very much for the workaround – much appreciated!

@bogdan Is there an ETA for a fix?

bogdan · February 24, 2020, 12:37pm

Hi @EricJacksch, we are still working on this. I don’t have precise ETA, but we will give our best to get this updated this week or early next.
