Need help in fixing some bug in a Rust app

Hi

I am looking for a Rust developer who can help in fixing a bug in an app. Following this task we can continue working on completing the project but for this specific project, we only need to fix the bug.

I am getting the following error:
thread 'tokio-runtime-worker' panicked at 'called `Result::unwrap()` on an `Err` value: IoError(Error { kind: UnexpectedEof, message: "failed to fill whole buffer" })', backend/src/handler.rs:185:94


This is related to the line:

let witness_membership = <MembershipWitness::deserialize(witness).unwrap();

Please note that I am using the crate: https://crates.io/crates/vb_accumulator

Please let me know if you have any question.

Many thanks,
Zak
