Cannot Decrypt #696

Closed czh-rot closed 1 month ago

czh-rot commented 1 month ago

The question is follows: the error occurs in line 128. image

Did you debug this? It seems you are calling Plaintext::set_zero on coefficient at index 0, but your Plaintext has coeff_count 0, so there are no coefficients at all (you are calling this constructor).

I was busy with other things in the past, so I didn't reply in time. I've figured out what the problem is, and a mismatch between the parameter input for decrypt and pt actually causes it.
