I saw this happened when I was on Node 10.3 (the earliest documented supported by cdk)


Not sure if the issue is as hinted by (node:16) ExperimentalWarning: The fs.promises API is experimental

I tried with node 11 or 13 and the issue was gone (and the latter warning was gone too)

I think the resolution for this issue should either drop support for Node 10.x or provide a solution that will work will old versions of Node.

Ah, thanks for that command line. I will binary search for the minimum required Node 10.x version now 😃

rix0rrrcommented, Apr 10, 2020

Running this to find the minimum required Node version:

docker run --rm -it node:10.15-slim bash -c 'mkdir thedir; env dir=thedir node -e "const fs = require(\'fs\'); fs.promises.mkdir(process.env.dir, { recursive: true }).then(() => console.log(\'ok\')).catch(e => console.error(e));"'

Well, the documentation actually just states that 10.12 is the first version that supports { recursive: true }, so that’s the one we NEED.

10.17 is the first one that doesn’t complain about fs.promises being experimental anymore, which I guess might be worth something. But for now I think we’re going to raise the minimum suggested version to 10.12.
