Hyperdrive fails to connect in `scheduled()` (but works over HTTP)

There's definitely something fishy here; without any changes, everything just started working again i.e. the DB connected. I refresh, and it's back to the above error with CF saying it can't read the HD connection string. Refresh 10 more times, same error. On the 11th time, it works 🤷

Hyperdrive fails to connect in `scheduled()` (but works over HTTP)

Thanks, really appreciate it. If it helps, I used to get this error every time I made code changes while testing schedules, i.e. the next time I visited the /__schedule endpoint after Wrangler's HMR had uploaded the changes. I'd then refresh, and it would work fine. But that first time, after code changes, I'd always get this. Now suddenly I get it constantly.

Hyperdrive fails to connect in `scheduled()` (but works over HTTP)

Just to be clear, with the above setup:

export default {
    fetch: (req, env) => console.log(env.db.connectionString), //exists
    scheduled: (evt, env) => console.log(env.db.connectionString) //undefined
}

export default {
    fetch: (req, env) => console.log(env.db.connectionString), //exists
    scheduled: (evt, env) => console.log(env.db.connectionString) //undefined
}

Hyperdrive fails to connect in `scheduled()` (but works over HTTP)

From the docs:

To access your production (remote) Hyperdrive configuration, pass the --remote flag

This is what I'm doing. My dev DB is remote, and is created as a HD, and I connect to it locally via --remote.

Hyperdrive fails to connect in `scheduled()` (but works over HTTP)

Hi - could you possibly elaborate? This is the setup I've had for over a year and it works perfectly over HTTP?

With the `scheduled` handler, what's the difference between waitUntil and just using async/await?

Thank you, much appreciated.

"SyntaxError: Unexpected end of JSON input" in wrangler-dist/cli.js

Much appreciated.
