[BUG] Chat Loses File Context After First Question When Using Embedding Without Vector Store

[marcosmarf27]

Describe the bug
The chat loses file context after the first question when using file upload (embedding) without vector store. After answering the first question related to the uploaded file, subsequent questions can no longer reference the file content, effectively losing all conversation context.

To Reproduce
Steps to reproduce the behavior:

1. Access Flowise chat
2. Upload a file using the embedding functionality
3. Ask a first question about the file content
4. Observe that the first question is answered correctly
5. Ask a second question related to the file
6. Observe that the chat can no longer reference the file content

Expected behavior
The chat should maintain the file context throughout the entire conversation, allowing multiple questions about the loaded file content without losing reference to it.
