Gmail File attachment error when using Copper extension

Hi there,

Over the past 2-3 days, I’ve been continually getting this error message on Gmail when trying to attach a file to a message by selecting “Upload from Computer”:
Failed to find the composer upload button

It's been coming up repeatedly and only eventually disappears if I reload the whole page, but this is making sending emails with attachments extremely slow and cumbersome.

It seems to mainly happen when I’ve used Copper to load a message template into an email, and then try to attach a file.

I’ve worked with our internal IT team to update Chrome, restart the browser, uninstall the Copper Chrome extension and reinstall it, but the error message continues to pop up. When the Copper extension is not installed in Chrome, or when I try a browser other than Chrome, I do not see the message pop up.


Any help would be much appreciated!

Hi @samrm, thanks for posting! Definitely sounds like something it up. The best thing to do is get in touch with our technical support team - they can help you troubleshoot based on your browser settings, etc.

Can you reach out to them using the in-app messenger icon?
