I am facing an issue when running cargo build in the jito-labs/searcher-examples project. The error message I receive is:
"called Result::unwrap() on an Err value: Custom { kind: Other, error: protoc failed: bundle.proto: This file contains proto3 optional fields, but --experimental_allow_proto3_optional was not set."
It seems to be a problem related to the proto3 optional fields. How can I resolve this issue and set the correct flag?
Thank you for your assistance.
