Hi,
A few days ago I bought the AWS File Upload plugin. Today I integrated it with the directions in the provided guide, but every time a file is uploaded I keep getting the message ‘Server responded with 0 code’. I’ve got the default (all public access) CORS policies and ACL setup, as specified in the Zeroqode guide.
What can I do to fix this?
can you please post a screenshot of the error you are getting?
Hi @dylang
Could you please post screenshots of your setup/workflow/plugin setup, aws and your app to help us debug it. thanks for understanding.

Dumitru.
I’m also having the same problem.
then same here: Could you please post Plugin Uploader’s proprieties as well as the console logs? thanks.
Hello, @tkassis
Please double check our setup documentation - https://docs.zeroqode.com/plugins/aws-file-uploader-plugin
And demo page setup: zeroqode-demo-02 | Bubble Editor
try reproducing all the setup and document actions, and test them out.
Also would recommend you try, uninstalling and reinstalling the plugin, place a new element of file uploader on page and give it a try.
Thanks.
Lately if everything was set as in our demo/doc method and still getting an error while uploading files, provide some screenshots better a video of you setup and screenshots from browser’s console log (ex:)
Also from current setup, I see you’re uploading file sizes bigger when in our demo, you should check your AWS S3 plan setup which should be able to upload sizable files.
Thanks.
Best,
Dumitru.
Hi Dumitru,
I followed the documentation exactly. I did it several times. Been trying for the past 4 days but no success. Here is a video of the error (including console): https://youtu.be/88qL3WvndCU
Thanks!
Hi @Dumitru I found what the problem was. It was a mispelling from my end. I had typed ‘ue-east-1’ instead of ‘us-east-1’ for the region in the plugin settings. All I needed was a good night’s sleep to catch that! (I think I checked the spelling about 10 times when I set it up).
I can relate to that 
unfortunately syntaxis check is still required with no-code building in rare scenarios like these
If you like our plugin, could you please rate it by going to Plugins tab in Bubble editor? You can find the plugin by name and give it as many stars as it deserves The more feedback we get, the more motivated to build great plugins 
Thanks! 
Hi,
I am also getting this error.
I tried everything you mentioned:
Still no luck. I am not sure what I’m missing.
Would you mind sharing an email address so I can add you as a collaborator?
Thanks,

Hello @emiledaou
Thanks for reaching out and sorry for the trouble.
If you’ve tried connecting the plugin with our IDs/Names and it worked, I believe it could be the AWS on your side which needs to be checked.
Can you try to create a new bucket and region accordingly and test again?
If that does not work for you, add support@zeroqode.com and the team will try to look at the issue.
Thanks for understanding.

Dumitru
Hello,
my plugin setup was working smooth for the past 4 years, never updated… then by nov 2025, it started to glitch,
updated the plugin to latest version
created workflow generation url flow
Now the plugin started working, but 4 out of 10 users reports server 0 code error, but retrying and refreshing does the job.
we created new iAM user, new keys, but its the same, not every time, not every user/pc, but this happens, have tried switching the internet to hotspot, changing browsers, but its still there…
Need Help.

Hello @yasirzxc ,
Thank you for reaching out and for flagging this issue!
It’s great to hear the plugin worked smoothly for 4 years - that’s quite a track record! However, a lot has changed and improved in that time, so we’ll need to dig into the current setup to identify what’s causing these intermittent “server 0 code” errors.
To help troubleshoot this, could you please share the following details:
Given that 4 years is a significant time span, there have been numerous improvements and changes to both AWS services and our plugin.
Once you share these details, I’ll be able to provide more specific guidance.
Looking forward to your response!
Best regards,
Support Team

@mina.rotari thanks for your prompt reply to my original message and for the follow-up. My bad, wasn’t able to reply.
Hi @yasirzxc,
Thanks for sharing those details.
We haven’t received similar reports from other users so far, so this might be tied to something specific in your configuration. Since the plugin has gone through quite a few updates over the past 4 years, there could be a setting or two that needs adjusting to align with the latest version.
Here’s what we’d recommend as next steps:
• Make sure you’re on the latest version of the plugin — given the long gap between updates, there may have been changes that address this kind of intermittent behavior.
• Compare your current setup with our demo page to see if anything differs in the configuration:
zeroqode-demo-02 | Bubble Editor
• Review the changelog for any relevant fixes or breaking changes that may have been introduced since your last update:
AWS File Uploader Plugin
If after going through those the issue persists, let us know and we can dig deeper. A short Loom video with the browser console open when the error occurs on one of the affected users’ machines would go a long way in narrowing this down.
Best,
