Building with functions fails due to compat flag/wrangler version

When I run bun dev locally it fires up my site using wrangler 3.90.0 (as defined in devDependencies and bun.lockb). Everything works nicely. When I then push the build environment tells me it's using wrangler 3.76.0 and gives me the following warning/error:

(deployment ID e4f93612-d702-48bb-8116-ab6476b4517a for any Cloudflare folks) My compatibility date is set to today (2024-11-23). I'm guessing at it being the older wrangler version, but I don't know, and I don't know how to update it in the build environment. Any ideas?
