Hi

While sending an image url as body for GPT4o, I am getting "431 Request header Filed Too Large". The same request with same image url works in gpt4 turbo. I am not able to find the exact cause for this. What could be the reason behind this difference? If the content was large, it should have not worked in gpt4 turbo as well.

    Solution:

    I did some more troubleshoot and found this error was due to some additional headers being send by the code sdk/postman which led to surpassing the maximum number of allowed headers. We updated our proxy code to allow only the mandatory headers which resolved the issue.

    If you have any other questions, please let me know. Thank you again for your time and patience throughout this issue.
