JSONDecodeError: Expecting value: line 1 column 1 (char 0)

[MathiasSong]

Hello,

I was able to run this app on my local machine (Windows 10). But, after I uploaded a PDF and API key, I am encountering the following error. Would you be able to help me resolve it?

Can you send me the detail messages shown in the terminals?

You need to modify the checkpoint path in windows system.

[MathiasSong]

@liuyixin-louis Could you please let me know which checkpoint path should be modified to what?

[liuyixin-louis]

Any path. Only if there are enough disks to store those checkpoint files.
