S3 Service API: Validation errors: [Prefix] must be of type string

    I’m having an issue with a site I just transferred to a new domain. Backups uploaded to my AWS S3 bucket with no problems on the old domain. I’ll try to be as detailed as I can.

    The new domain is in the same general environment, same hosting account, but a different addon domain. Before the wordpress installation was at domain.com and now it is at another-domain.com/folder/. The server path changed from …/public_html/domain.com/ to …/public_html/another-domain.com/content/.

    To keep things simple, I’m backing up the database by itself, and the backups are only 1-2MB and only takes about 15 seconds to complete. The backup seems to be created, it connects to the S3 bucket, checks for “not aborted multipart Uploads” and then shows the error message. Here is a snippet from the log:

    1. Trying to send backup file to S3 Service …
    Connected to S3 Bucket “backups” in
    Checking for not aborted multipart Uploads …
    ERROR: S3 Service API: Validation errors: [Prefix] must be of type string

    It tries three times and fails each time. If I turn off multipart upload, then it works fine. It worked before with multipart upload and I think this is better for the files backups, which are a lot bigger (~70MB).

    The files backup takes longer, and I have Reduce server load set to maximum, and (I can’t find where the setting was) it is set to restart on each step, so it takes 600-800 seconds. Maximum script execution time is set to 300 seconds, and after that it says “Restart after 298 seconds.” and keeps going.

    What could be the cause of the multipart upload problem?

    The Folder in bucket field is empty.

    I thought it was localized to just the one site, but now this issue is occurring on all of the sites I manage (or at least several that were scheduled to run during the last two days), all with the same error, and nothing changed on those sites other than updating the plugins.

    Thanks Daniel! I look forward to the update.

    Release 3.1.4 is out with a fix.

    Great! That seems to have fixed it. Thanks for the quick fix!
