Hi, tried many times, can't get chat gpt to pull up old messages

{
"error",{
{"message" Addition properties are not aloud ('messages.1' was unexpected)-'messages.1'",
"type"invalid;, "invalid_request_error",
"param", null,
"code",null
}
}
I am able to ask a question, I then get a reply. Then when I ask a follow up question, I get an error. Any help would be great. It’s added the 1st question and answer in to data along with my reply, after that I get error.
