I believe you need to escape with

await $`${{raw: str}}`

With your test code:

import { $ } from 'bun'

// [case: 1] - no need to escape
const a = $`echo hello`
await a

// [case: 2] - doesn't work as not escaped
const str1 = 'echo hello'
await $`${str1}`

// [case: 3] - works when escaping
const str2 = 'echo hello'
await $`${{raw: str2}}`

And you can see case 3 works (but case 2 doesn't):

You need to escape it, as described.
