Hi, I’m trying to generate proof with Noir JS for a linear regression circuit, but the issue is for same circuit (with dataset size changed) with fewer data size, the proof is generated and verified correctly, but when I increase the data length I encounter this error.

Error [RuntimeError]: null function or function signature mismatch

Since this is part of an ongoing research project, I am unable to share the exact source code. However, I can provide an overview of the circuit. It’s a 2D linear regression model where the inputs are two arrays, X (independent variable) and Y (dependent variable), both of a fixed length and of type i64.

a colleague of mine faced a similar issue. its likely a wasm error when the constraint size is too large (probably a wasm limit error throwing something else).
