用户在第1页上传文件，网站会将其重定向到第2页，在那里他们可以点击触发服务的按钮。我试图为每个用户上传创建一个唯一的URL，我知道错误与HTML页面2表单中的{% url 'initiate_transcription' session_id %}有关，但我不确定要更改什么。代码如下：
urls.py:

from django.urls import path
from . import views

urlpatterns = [
path("", views.transcribeSubmit, name = "transcribeSubmit"),
path("init-transcription/<str:session_id>/", views.initiate_transcription, name = "initiate_transcription"),
]

views.py:

JS第1页：

const fileInput = document.querySelector('#transcribe-file');

fileInput.addEventListener('change', function (event) {
    if (event.target.files.length > 0) {
        console.log(fileInput.value);
        const fileName = event.target.value;
        const fileExtension = fileName.split('.').pop().toLowerCase();
        const allowedExtensions = ['m4a', 'wav', 'mp3', 'mpeg', 'mp4', 'webm', 'mpga', 'ogg', 'flac'];

        if (!allowedExtensions.includes(fileExtension)) {
            const uploadField = document.querySelector('.transcribe-file-label');
            const originalLabelText = uploadField.innerHTML;
            uploadField.style.color = '#ad0f0f';
            uploadField.textContent = 'Invalid file type. Please try again';

            setTimeout(function () {
                uploadField.style.color = '';
                uploadField.innerHTML = originalLabelText;
                // Clear the file input field
                fileInput.value = '';
                return;
            }, 5000);
        } else {

        const form = document.querySelector('form');

        const xhr = new XMLHttpRequest();
        const formData = new FormData(form);
        xhr.open('POST', form.action);

        xhr.upload.onprogress = function (event) {
            if (event.lengthComputable) {
                let percentComplete = (event.loaded / event.total) * 100;
                let progressBar = document.getElementById('myBar');
                progressBar.style.width = percentComplete + '%';
                console.log('Upload progress: ' + percentComplete + '%');
            }
        };

        xhr.onload = function () {
            if (xhr.status == 200) {
                console.log('Upload complete');
                const response = JSON.parse(xhr.responseText);
                // Update the content of the current page with the HTML from the server
                if (response.redirect) {
                    window.location.href = response.redirect;
                }
                //document.body.innerHTML = response.html;
            
            } else {
                console.error('Upload failed');
            }
        };

        xhr.send(formData);
    }
}
});

下面是错误：

NoReverseMatch at /transcribe/init-transcription/854eae4d-3167-4e45-8b17-20a14b142aad/
Reverse for 'initiate_transcription' with arguments '('',)' not found. 1 pattern(s) tried: ['transcribe/init\\-transcription/(?P<session_id>[^/]+)/\\Z']

如果有必要，我可以提供追踪。
