Validation Error in Assistant API type=value_error.jsondecode

API Bugs
1

I am trying to get Assistant API to compose an short summary essay from a input of about 10 paragraphs of text , each paragraph being a 20-30 words length. Not a whole lot of data perhaps

I randomly get this error sometimes.

1 validation error for Request body → 1103
Invalid control character at: line 1 column 1104 (char 1103) (type=value_error.jsondecode; msg=Invalid control character at; doc={ …

Has anyone faced this ? I am not able to figure out anything. If I shorten the text inputs at some point in time the error disappears - my total length is only 700 words - so it can be breaking GPT down I hope,

Well it turns out that the content that one feeds to createMessage (GET/v1/threads/thread_xxx/messages) is sensitive to presence of control characters like newline, tab, or double quotes - even if they are extracted from a valid json and escaped
The problem is CreateMessage API method may or may not throw an exception. Instead of throwing an exception it may return ajson of the following format

{
“error”: {
“message”: “1 validation error for Request\nbody → 42\n Expecting ‘,’ delimiter: line 1 column 43 (char 42) (type=value_error.jsondecode; msg=Expecting ‘,’ delimiter; doc={… }; pos=42; lineno=1; colno=43)”,
“type”: “invalid_request_error”,
“param”: null,
“code”: null
}
}

So the safe approach is to do both things after creating a message-

  1. check if returned json object has key “error”
  2. catch exception if thrown

This way you will be 100% sure that your messge has been created with the content you have provided and then you may proceed to call the RUN method
