Problem Importing old Penpot Files into Version 2

Hello,
I am using a PenPot 2.0 self-hosted and I have it up and running and can import some of the PenPot templates I have (e.g., Material UI), but I cannot import any of the old files I created using Penpot 1.19.0. I receive an error saying, “There was a problem importing the file. The file wasn’t imported.”
Has anyone else had this experience, or know of anything I can try to fix this? I haven’t been able to find a lot of information on backwards compatibility, other than that there are issues with components.
Thanks in advance for any help or insight anyone can provide!
**Update - In the console log I am getting an error saying that the request body is too large. Is there any way to increase the allowed size of the import?
