[Loaders] Runtime does not respect import ... with { type: "json" }

[A-D-E-A]

What version of Bun is running?

1.1.17+bb66bba1b

What platform is your computer?

Linux 5.15.133.1-microsoft-standard-WSL2 x86_64 unknown

What steps can reproduce the bug?

Use a test json file with any extension other than "json".
For example, "data.any":

{ "hello": "world" }

Then, write index.ts:

import data from "./data.any" with { type: "json" };
console.log(json);
console.log(typeof data);

What is the expected behavior?

The console should show

{
  hello: "world",
}
object

What do you see instead?

The console shows

/path/to/file/data.any
string

Additional information

It works for other types, such as "toml", "text" or "file". Only "json" (to my knowledge) is affected.

recategorizing this as not a bundler bug but a runtime bug. a workaround to this would be to temporarily use bun build --target=bun.
