React fine uploader not displaying thumbnails and progress?

I have trouble setting react-fine-uploader to work properly. I’m using react-fine-uploader low level components, and after I choose images thumbnails won’t show although I’ve done everything that docs say.

Here are versions I’m using

"fine-uploader": "^5.16.2",
"fine-uploader-wrappers": "^1.0.1",
"react-fine-uploader": "^1.1.1",

Here is my uploader setup:

const uploader = new FineUploaderTraditional({
options: {
  chunking: {
    enabled: isChunkedUpload,
  },
  request: {
    method: 'POST',
    endpoint: `${process.env.REACT_APP_API_URL}/api/images`,
    customHeaders: { Authorization: `Bearer ${accessToken}` },
    filenameParam: 'name',
    uuidName: 'id',
    totalFileSizeName: 'size',
    inputName: 'image',
  },
  multiple: true,
  callbacks: {
    onComplete: (id: number, name: string, response: object) => {
      console.log(id, name, response);
    },
    onSubmitted: (id: number, name: string) => {
      const newSubmitedFiles = submitedfiles;

      newSubmitedFiles.push(id);
      setSubmittedFiles(newSubmitedFiles);
    },
    onError: (id: number, name: string, errorReason: string, xhr: any) => {
      console.log(id, errorReason, xhr);
    },
  },
},
});

And here are components that I’m using:

     <Dropzone
        className="dropzone"
        style={{ backgroundColor: isDragOver ? 'red' : '' }}
        uploader={uploader}
        multiple
        onDropError={(errorCode: string, errorData: string) => console.log(errorCode, 
        errorData)}
      >
        <span className="dz-message">
          Drop Files Here
        </span>

        {submitedfiles.length ? submitedfiles.map((id) => (
          <div className="dz-preview" key={id}>
            <Thumbnail
              className="dz-image"
              id={id}
              fromServer={false}
              uploader={uploader}
            />
            <CancelButton id={id} uploader={uploader} />
          </div>
        )) : null}
      </Dropzone>
