Hi,

I'm trying to bump one route up to 30 minutes (1800 seconds) using the extended max duration beta, but every deploy fails at the very end with:

Builder returned invalid maxDuration value for Serverless Function "system/download". Serverless Functions must have a maxDuration between 1 and 800 for plan pro.

I'm on Pro, Node 22.x, Fluid compute is enabled in project settings, the route runs on the Node runtime (no edge export), and maxDuration = 1800 is set in the route file itself rather than as a project default. I've also redeployed with the build cache off. Nothing changes, the build compiles fine, it's only the function validation step that rejects it.

I opened a support case and they confirmed Fluid compute is on for my project, but closed it as out of scope since the feature is in beta, and pointed me here.

Is there anything else required to unlock durations above 800s? An allowlist, a team-level flag, an env var opt-in? Or could a project-level Default Max Duration be overriding the per-function value while the beta is on?

Happy to share the deployment ID or full build log if that helps.

Thanks
