💻 Code

see the repo: https://github.com/stefanprobst/issue-ts-preserve

🙁 Actual behavior

when running tsc --noEmit in the example repo, i see this error message:

index.ts:2:31 - error TS1324: Dynamic imports only support a second argument when the '--module' option is set to 'esnext', 'node16', or 'nodenext'.

2  return import("./data.json", { with: { type: "json" } });
                                ~~~~~~~~~~~~~~~~~~~~~~~~~~


Found 1 error in index.ts:2

🙂 Expected behavior

i had expected module: "preserve" to work with dynamic imports + import assertions.

when setting module: "esnext", i see no error message
