AWS Plugin - Files not landing in AWS

jsteven2103 · October 31, 2024, 11:07pm

Hi, the AWS File Uploader is working great on a client’s app, but we’ve had a strange issue come up lately.

We are using the NoGUI File Uploader and we have the settings for the File to upload instantly and then attach the URL of the file to the Bubble Object the user is creating. This has worked well with all the users so far. However, we have one user that whenever they upload a file, the AWS URL gets generated and the URL attaches to the Bubble object, however the File never appears in our AWS Folders for this particular user. The Bubble Logs say the File Uploaded and the URL is attached in our Bubble Database, but it’s not in AWS?

When I run as that particular user’s account I’m able to upload AWS Files, and all our other users are as well.

Because this only happens on one particular user, is it possible that there is some type of Firewall blocking going on this user’s device or Organisation Firewall? Has anyone else encountered this scenario where the URL is generated and the Logs say a File was uploaded… but no file appears in your AWS Bucket?

Thanks in advance - I know it is a strange and weird request.

Hello @jsteven2103,

Thank you for reaching out to us.

This is indeed an unusual issue, especially since it only affects a single user. It’s great that you’ve narrowed it down to their account. Here are some possible causes and troubleshooting steps to help pinpoint the issue:

Browser and Cache Issues

Sometimes browser settings, especially on highly restricted corporate devices, can cause issues with uploads. Ensure that the user’s browser is up to date and that they have cleared their cache and cookies.
Have them try a different browser or device to check if the problem is browser-specific.

Firewall or Network Restrictions

As you mentioned, since this issue is isolated to a single user, it’s possible that their organization’s firewall or network security settings are blocking uploads to AWS. Some firewalls and VPNs might interfere with direct file uploads to external servers.
Ask the user to attempt the upload from a different network (like their home network) or temporarily disable their firewall/VPN to see if it resolves the issue. If this works, they may need to whitelist the AWS S3 endpoint or IP range.

Permissions and Bucket Policies

Check the AWS S3 bucket permissions and policies to confirm there are no specific conditions affecting this user. Although it’s less likely given the isolated nature of the issue, it’s worth verifying that the S3 bucket policies haven’t inadvertently restricted access for specific devices or locations.

AWS Region-Specific Issues

Although rare, there could be regional connectivity issues. Check which AWS region you’re using for storage and, if possible, confirm if there are any ongoing issues or try switching regions for testing.

AWS Temporary URL Generation

If you’re using pre-signed URLs, it’s possible that the upload request is not completing due to network or device restrictions.
Check for any error codes or logs on AWS related to this user’s attempted uploads. AWS may have captured logs that could provide insights if there’s a request made but not fulfilled.

Bubble Workflow Debugging

Review the Bubble workflows and actions triggered during file upload for this user to ensure there’s no condition specific to their profile that could be interrupting the process.
Consider adding logging to each step of the upload process for deeper insight.
