References are not shown properly in UI

Have run the package from main branch and created a bot with PDF documents. There are three nodes shown as references for the answers but they are empty and not showing the part of PDF as source/reference (Screenshot attached)

Thanks @mohdamir. This should only happen if you're using a Typescript backend, but not with Python. The reason is that Typescript is not adding any file metadata; I added a patch for this (run-llama/LlamaIndexTS#758), which will be released with the next LlamaIndexTS version.

Meanwhile, if you're using a Typescript backend, I filter out source nodes without metadata, see 8b81b17

Thanks @marcusschiesser. Looking forward for the next release.
