What steps will reproduce the bug?

Start the REPL with node, then run this line:

var { ...rest } = await {}

How often does it reproduce? Is there a required condition?

100%

What is the expected behaviour? Why is that the expected behaviour?

No error should be thrown.

What do you see instead?

The following error:

Uncaught TypeError: Cannot read properties of undefined (reading 'type')

Additional information

The issue is related to how the REPL handles top-level await.

Hi! Could you possibly reformat your issue, it's a bit hard to read when the markdown and code are intertwined

I'm able to reproduce:

➜  ~ node          
Welcome to Node.js v22.2.0.
Type ".help" for more information.
> var { ...rest } = await {}
