If you look again at the error message you see that it asks you to contact help at help.openai.com rather than at aiprm.com which tells you which system or part of the system is throwing the error. In this case, this is a ChatGPT error, rather than an AIPRM error.
If you want to be entirely certain, you can temporarily disable the AIPRM extension and try the same sort of action without it, just to be sure it isn’t somehow some bug in AIPRM that’s passing bad code or an outdated method to the ever-changing ChatGPT system. Obviously, you should also check that you have the latest version of AIPRM, since the versions do change as the ChatGPT methods change and get updated, breaking previous ways of interacting.
If you find that the error only occurs while using the latest version of AIPRM, and you have no other extensions for ChatGPT installed that might be causing conflicts*, screenshot anything you think can help identify what is going wrong and email the AIPRM team at hello@aiprm.com
