Error message for invalid config is misleading

[grimly]

Describe the bug

I am using swc with rollup, therefore I am using the API, not the CLI.

I tracked down my issue to the use of the transform function from @swc/core.
I've removed all the code I could to narrow down the source of my problem.

Here is the code to run with node directly :

const { transform } = require('@swc/core');

const filename = 'index.ts';

const code = `
export async function getDependency(): Promise<any> {
  return import('./dep').then(({dependency}) => dependency);
}
`

const options = {
  jsc: {
    parser: {
      syntax: 'typescript',
      dynamicImport: true
    },
    externalHelpers: true,
    target: 'esnext'
  },
  sourceMaps: true,
  filename
}

transform(code, options)
  .then(console.info, console.error)

The following error prints immediately:

error: import(...) expressions requires `jsc.parser.dynamicImport` to be true
 --> index.ts:3:10
  |
3 |   return import('./dep').then(({dependency}) => dependency);
  |          ^^^^^^

The returned promises emits an error which prints as the following:

[Error: failed to process js file

Caused by:
    failed to parse module] {
  code: 'GenericFailure'
}

Expected behavior
The code should compile

Version
The version of @swc/core: 1.2.51

target: 'esnext' is wrong. You should use target: 'es2020' instead.
Error message seems misleading, though.

Indeed this fixed my problem. Thank you very much.

Should I leave this issue open until the error message is clearer or not ?

[kdy1]

Please leave it. I'll change the title.
