Ubooquity container continues to fail while reading /books folder

Hi,

I am running the ubooquity container on Raspberry pi 4. However, whenever I mount the books folder to /books the container keeps on failing with below error. Although, the same folder when mounted to /files does not cause any problem.

I am unable to upload the log file.

I have no clue what this error is about.
Can you help with this?

Thanks,
