**Original Discord Post by h3ll51ng | 2024-10-18 12:53:22** Hello, I have integrated a convai character with lipsync in my unity scene. Everything works as it should in editor but when building for iOS through xcode i come across gRPC errors. I went through the documentation and made sure the necessary gRPC runtime files are available as suggested but the build still fails. ---
