Prod deploy mysteriously failing with 400 Bad Request: UnexpectedAuthHeaderFormat

I was able to successfully deploy my project on Vercel when I last changed it on 5 Mar 2025, but I made a frontend change today (no Convex changes) and the convex deploy step is now failing with this error:

400 Bad Request: UnexpectedAuthHeaderFormat: Unexpected auth header format. If you are trying to use preview deployments, please generate a new key in the Convex dashboard.

400 Bad Request: UnexpectedAuthHeaderFormat: Unexpected auth header format. If you are trying to use preview deployments, please generate a new key in the Convex dashboard.

I generated a new deploy key (and noticed that this new one had a different format, e.g. it was shorter - interesting) and updated my CONVEX_DEPLOY_KEY env variable in Vercel, but still no dice. Any other tips?

How to generate random base64 in mutation

I have a "create API key" mutation and I'd like to generate a base64 API key, but it seems the btoa provided by the Convex function runtime fails if the string contains values outside a certain range. This newApiKey() function works in browsers but fails in Convex: https://www.typescriptlang.org/play?#code/GYVwdgxgLglg9mABGApgdwIIAcYGkUCeAFAJQBciAzlAE4xgDmiA3gFCKID0niDKqNAIZQUiAMwAmALQAjAiMQYACgElEAa0LtEEBNURyRlRAF5FNIQQB0wGnAC2RZogA2-BlAAWFSYgC+ADSIpKYAfIgAssKeNi5wcDREUV5WQmAAJg4hAFSIEgCsAGwkJADc2tyI-LrpovSIAKoASgAyUpSCwKIygpQohQAsFTxEfaKeUFBYlGTc-FZoMOowWCjpMIJWCQyci8ucAEK9-QMAxABqgnSCYFCUAPqUIPb2VwT3UIIybiTaNChQEA0JAyKBwQREADKtHoDBsdnsAGFPFdEXBalZBFgsC5iGAQC4XEFDChKCVtBxUigcYIICgiJwADoAak4DCCAHIpBzfhxKf8aXSGYzuOzEBz7jyKYgqYL6ZwTGzOVK-KxWII3DQoERUJgcPhiCUgA Is there an alternative way to generate a random base64 string?

Support for `convex import` from a snapshot export?

When I try to use convex import to restore a table snapshot I just downloaded, I get this error:

500 Internal Server Error: InternalServerError: Your request couldn't be completed. Try again later.

500 Internal Server Error: InternalServerError: Your request couldn't be completed. Try again later.

Adding --append doesn't help. I'm using Convex 0.12.2
