Implementing completely offline use of tesseract.exe resulted in an "Error opening data file"/ eng. traineddata "issue

[22480]

Describe the bug：
I want to achieve fully offline use of tesseract.js, so I will:

const recognizeText = async (imageUrl: string) => {
const worker = await Tesseract.createWorker("chi_sim", undefined, {
workerPath: "/tessdata/tesseract.js/dist/worker.min.js",
corePath: "/tessdata/tesseract.js-core",
langPath: "/tessdata/tesseract-lang",
logger: m => console.log(m),
})

    const {
        data: { text },
    } = await worker.recognize(imageUrl)
    setRecognizedText(text)

    await worker.terminate()
}

To Reproduce：
Steps to reproduce the behavior:

1. Create a tessdata folder in the public folder
2. Place local resource files in this folder：
   tesseract-lang、tesseract.js、tesseract.js-core
3. Run

Complete code
const inputRefOCR = useRef(null)
const [imageData, setImageData] = useState("")
const [recognizedText, setRecognizedText] = useState("")

const handleCapture = () => {
    if (inputRefOCR.current.files && inputRefOCR.current.files.length > 0) {
        const file = inputRefOCR.current.files[0]
        const reader = new FileReader()
        reader.onload = e => {
            setImageData(e.target.result)
            recognizeText(e.target.result)
        }
        reader.readAsDataURL(file)
    }
}

const recognizeText = async (imageUrl: string) => {
    const worker = await Tesseract.createWorker( {
        workerPath: "/tessdata/tesseract.js/dist/worker.min.js",
        corePath: "/tessdata/tesseract.js-core",
        langPath: "/tessdata/tesseract-lang",
        logger: m => console.log(m),
    })


    const {
        data: { text },
    } = await worker.recognize(imageUrl)
    setRecognizedText(text)

    await worker.terminate()
}

Console error display：

Expected behavior：
Implement fully offline use of Tesseract.js
