pdfme: Cannot import `generate` in my Sveltekit project

Describe the bug

I try to integrate pdfme into my Sveltekit project. I copy paste the example code from the doc to the page.svelte and get an error SyntaxError: Cannot use import statement outside a module.

To Reproduce

Please check the integration in this online Sveltekit demo: https://www.sveltelab.dev/sqnh3ssj6s6te4m, or copy the below code in page.svelte.

<script lang="ts">
  import { generate, BLANK_PDF } from '@pdfme/generator'

  const template = {
    basePdf: BLANK_PDF,
    schemas: [
      {
        a: {
          type: 'text',
          position: { x: 0, y: 0 },
          width: 10,
          height: 10
        },
        b: {
          type: 'text',
          position: { x: 10, y: 10 },
          width: 10,
          height: 10
        },
        c: {
          type: 'text',
          position: { x: 20, y: 20 },
          width: 10,
          height: 10
        }
      }
    ]
  }

  function genPdf() {
    let date_now = new Date()
    // Generate the PDF ticket
    const inputs = [{ a: 'a1', b: 'b1', c: 'c1' }];

    generate({ template, inputs }).then((pdf) => {
      console.log(pdf)
      // Browser
      const blob = new Blob([pdf.buffer], { type: 'application/pdf' })
      window.open(URL.createObjectURL(blob))
    })

    console.log('finish pdf')
  }
</script>

    <button  on:click={() => { genPdf() }}>Generate PDF</button>
