9 months ago Hi, @pengxichen! I'm Dosu, and I'm helping the gpt4-pdf-chatbot-langchain team manage their backlog. I wanted to let you know that we are marking this issue as stale.
From what I understand, you opened this issue regarding a fatal error related to a JavaScript heap out of memory. Unfortunately, there hasn't been any activity or comments on the issue since you opened it, and it remains unresolved.
If this issue is still relevant to the latest version of the gpt4-pdf-chatbot-langchain repository, please let the team know by commenting on the issue. Otherwise, feel free to close the issue yourself, or it will be automatically closed in 7 days.
Thank you for your understanding and contribution to the project! Let us know if you have any further questions or concerns.
