[Bug] Upload button not working now.

[hkvincent]

After the commit below, the upload button only works for CSV and image files.

feat: use create-llama chat session (https://github.com/run-llama/chat-llamaindex/pull/94[)](https://github.com/run-llama/chat-llamaindex/commit/5c16a343eab3daaefa363a8d450df972757f64ff)

I'm not sure why, but after this commit, the application is using the file-uploader located in the "cl" directory instead of its own. This seems to be where the issue lies.
personal (Workspace)/e:\Workspace\AI\llm\rag\chat-llamaindex\app\components\ui\file-uploader.tsx:61

const handleUpload = async (file: FileWrap) => {

personal (Workspace)\Workspace\AI\llm\rag\chat-llamaindex\cl\app\components\ui\file-uploader.tsx:62

  const handleUpload = async (file: File) => {
    const onFileUploadError = onFileError || window.alert;
    const fileExtension = file.name.split(".").pop() || "";
    const extensionFileError = checkExtension(fileExtension);
    if (extensionFileError) {
      return onFileUploadError(extensionFileError);
    }

    if (isFileSizeExceeded(file)) {
      return onFileUploadError(
        `File size exceeded. Limit is ${fileSizeLimit / 1024 / 1024} MB`,
      );
    }

    await onFileUpload(file);
  };

props.onFileUpload is always undefined.
After committing #94 , only the image and CSV file are functioning properly.

great catch. yes we're working on adding PDF upload now to create-llama first - it will then be automatically in Chat LlamaIndex

@hkvincent file upload is now implemented in #101 - it's not working on https://chat.llamaindex.ai/ at the moment though as it's requires a dedicated vector store (coming soon)
