panic: index out of bounds: the len is 1 but the index is 1

[Sinderella]

I am unable to provide the PDF file as it contains a lot of PII. Please let me know if it's really required, I can try to redact as much as I can. Cheers!

Do you know what tool was used to make the PDF?

[Sinderella]

I don't know which exact tool was it, but exiftool gives me the following:

Creator                         : Vault Rendering Engine
Producer                      : Rendering Engine 7.4.1.9
