[BUG] issue with parsing message history in RAG

[SilverSeed93]

Pre-check

• I have searched the existing issues and none cover this bug.

Description

I have uploaded a document into PGPT but RAH is having issues with things like JSON in the history. The first time I query the document it works. The second time I query the document, it does not work and I get the following error:
Invalid format specifier ' "Who was George Washington?", "answer": "The first President of the United States of America." ' for object of type 'str'

Source document is formatted Markdown and ingested without error.

This seems to only happen in RAG. If I switch to other tabs and ask it to generate things like JSON and Scripts it works fine. After encountering the error, if I switch from RAG to the other modes it will also still work.

It does break the other way around. If I ask chat to give me an example of JSON format and then go into RAG and query anything it will break and throw the error.

Steps to Reproduce

1. Import a document
2. Select RAG
3. Send prompt: Create question and answer pairs from the document in JSON format using only two keys Question and Answer.
4. Observe results.
5. Send prompt: Create question and answer pairs from the document in JSON format using only two keys Question and Answer.
6. Error is produced.

Another you can try is to upload any decent sized python script.

1. Import a document
2. Select RAG
3. Send prompt: Print the script document into a code block
4. Observe results.
5. Send prompt: What does the script do?
6. Error is produced.

Expected Behavior

parse the history to stop escaping

Actual Behavior

invalid format specifier error thrown

Environment
