A dynamic import callback was not specified

[jmatsushita]

Getting this error when using prettier from the prettier-vscode extension. The error is also reported here prettier/prettier-vscode#3007 but seems to originate from prettier:

["ERROR" - 13:22:40] Error handling text editor change

Strangely, I did find a bizarre workaround. When I patch the prettier/index.cjs file to await import("./index.mjs"); I get an error on module load

/Users/jun/dev/workshop/iios/node_modules/prettier/index.cjs:600
var prettierPromise = await import("./index.mjs");
                      ^^^^^

SyntaxError: await is only valid in async functions and the top level bodies of modules

But somehow the extension recovers and after that formatting works (though the vscode extension logs show the error each time). Not a recommended workaround, but maybe it will help identify the underlying issue?

EDIT: this breaks other things, do not use!

👋 @jmatsushita!

Prettier v3 alpha does not work in VS Code (yet) – see prettier/prettier-vscode#2947 (comment) and below for details.

Let’s close this issue because this repo is related to Prettier core, not its integration. I am also waiting for VS Code support for the upcoming v3 🤞

Great thanks 🙏
