Issue with Uploading User Data to Playground Assistant and Solution

I wanted to upload my own user data to the Playground Assistant, but I discovered that it was being rejected. After some research (I halved the file until I was able to pinpoint the issue), I found that the rejection was triggered by this line. After removing the “[”, it worked.

messages = conversation_history if gedaechtnis_nutzen else [{“role”: “user”, “content”: question}]

Nothing to discuss here; I just wanted to share this in case it might be useful for someone someday.

Due to my lack of English skills, I asked GPT to correct the previous text. Additionally, GPT-4o started a code interpreter to display this line of code.
