Describe the bug

I have a very basic ingestion flow.

In version 3.0.4 this worked, and I was able to upsert to pinecone successfully. However, I couldn't use anthropic's new chat models due to a different bug, so we decided to upgrade our instance to 3.1.1. After upgrading, this ingestion flow no longer indexes anything.

Over the course of trying to debug this, I tried manually providing a file in the File Loader node, and hitting the Upsert button directly within Flowise. This also indexed nothing, and showed all zeros. I then replaced each node one at a time to no avail, but after setting it back to the original flow, this same manual scenario now worked. I think deleting and re-adding the connections between nodes somehow got me past some problem. Anyways, I then went to upload a different file from my web app hooked up to this flow, with a File still specified in the File Loader node, and I was successful. However, it just upserted that static file over and over again, not the one I was providing in the request. I removed the defined file from the File Loader node, and I am back to square one where the call is successful but nothing is indexed/added.

To Reproduce

1. Be on version 3.1.1 and create an ingestion flow similar to mine.
2. I have the File and Additional Metadata set to overridable in the override config.
3. Make a multi-part form data request with a File provided. (I am using RestSharp in .NET)

var request = new RestRequest($"/api/v1/vector/upsert/{chatflowId}", Method.Post);
request.AddFile("files", fileBytes, fileName, mimeType);

4. Nothing gets indexed.

Expected behavior

I would expect the file uploaded to ingest the file provided in the request, and index and chunk it, and send that to pinecone, as it did before.
