Error in TypeScript Playground

I’m seeing an console error in Playground using TypeScript. First line is a message, second is a warning or error.

BJS - [09:55:33]: ATA is in flight, waiting for completion before creating runner…
BJS - [09:55:35]: ATA did not complete within timeout, proceeding with runner creation anyway

Am I doing something wrong?

My guess is that typescript compilation is an API call that doesn’t respond within the timeout.

Things started working after I set my mobile browser to “Desktop site”.
