FWIW on this, I've just tried (everything fully patched and upgrade beforehand - yes, I know "latest" isn't a version, but there are too many variables at play here):

• Ubuntu 22.04.4 physical machine #⁠1 - Chrome, Firefox native, Firefox Snap, Opera
• Ubuntu 22.04.4 physical machine #⁠2 - Chrome, Firefox Snap
• Ubuntu 22.04.4 VM (Ubuntu 22.04.4 #⁠1 host, Virtualbox) - Chrome, Firefox Snap
• Windows 10 VM (Ubuntu 22.04.4 #⁠1 host, Virtualbox) - Chrome, Edge, Firefox
• Windows 10 VM (Ubuntu 22.04.4 #⁠2 host, virt-manager) - Chrome, Edge, Firefox
• Windows 11 physical - Chrome, Firefox, Opera
• Android 14 physical - Chrome, Firefox, Opera, DuckDuckGo

I've also toggled VPN on/off where applicable (Opera), I've used private/incognito tabs, I've switched off my PiHole and also toggled between cellular and LAN to eliminate both local config and ISP issues. Most of these devices have never been used to access the CMS before, so there should be no cached... well, anything (plus several of these were refreshed or clean browser installations as well).

All failed with (browser-specific presentation variations of) the same error, as above. It's not looking like a client error, then, as I think that comprehensively eliminates most variables (including browser engine).

As far as I can tell this was introduced with 3.1.0 - we've reverted to the version before that now and it started to work again.

I had this exact error message but probably not the same cause as OP. The workaround noted by razzeee worked.

But ultimately the fix for me was to use decap-cms-app - not decap-cms (I'm using the "install with npm" method instead of cdn)

[razzeee]

I'm using decap-cms-app so, it doesn't seem to be what's solving this.

The latest version also still has this bug happening.
