anvil.server.RuntimeUnavailableError: Failed to launch server runtime from Tutorial: Data Bindings

I was getting this error while following the last part (chapter 4) of Tutorial: Data Bindings. I wasn’t sure what could be causing the problem, then I cloned the app from the tutorial and when I run it I get the same error. I’ve restarted the app and tried using a different browser and still get ‘anvil.server.RuntimeUnavailableError: Failed to launch server runtime’ . Any ideas what the problem is?

it would be easiest if you just shared the clone link since it’s a specific tutorial step.

I was also facing the same issues with the app I’m currently working on. I tried running my other apps, and they all have this error, which hasn’t occurred before.

The error says ‘Failed to launch server runtime’

Thanks for the link. When I run the link, I didn’t get any error. Did you do anything specific to get the error to appear?

Are you currently on a plan by any chance? I’m using a free plan, and I tried running the app, and it didn’t work.

yeah, I have a paid for plan (don’t remember which off the top of my head). I’ll check on my alternate account that’s not paid when I get home.

Update: I tried it with my free plan account and it also launched. I don’t know if it is something intermittent or something else.

I think this might need Anvil Staff.

Yep, that was an outage, affecting only the Free plan - now resolved. Can you try again please, @splynch02?

(Unfortunately, this failure mode also incinerated the information we’d be using to debug it - we’ve added a bit more monitoring that would have let us (a) see this coming and stop it before service was interrupted, and (b) get more information about what’s going wrong).
