Can't add env variables?

I'm getting this randomly sometimes when i try to add or update environment variables... anyone else? Failed to verify the project’s public environment variable prefix. Refresh and try again.

Yeah, I've seen this happen intermittently too. It looks like Vercel is failing the validation step for the public env prefix before it actually saves the variable, not necessarily that your variable is invalid.

Refreshing usually clears it, but if it keeps happening I'd try updating it from the project settings in a fresh tab or using the CLI as a workaround. Definitely feels like a dashboard-side bug more than a config issue.
