What is broken?

Bug Report: session.promptAsync throws "_zod.def" error

Describe the bug
When sending a prompt via Telegram bot @hey_maxfield_bot, the session.promptAsync call fails with error: "undefined is not an object (evaluating 'n._zod.def')"

To Reproduce

1. Start OpenCode server: opencode serve --port 4096
2. Start Telegram bot: opencode-telegram start --daemon
3. Send any prompt via Telegram bot
4. Error occurs immediately

Expected behavior
Prompt should be sent to OpenCode and session should respond

Environment

• Bot version: 0.19.3 (npm package)
• Bot SDK: @opencode-ai/sdk@1.14.33
• OpenCode version: 1.14.33
• Platform: macOS

Logs

[INFO] [Bot] Calling session.promptAsync (start-only) with agent=build

Notes

• Bot connects to OpenCode server successfully (health check passes)
• Problem appears to be in SDK schema validation for promptAsync
• User ID whitelist works correctly

Steps to reproduce

1. Start OpenCode server: opencode serve --port 4096
2. Start Telegram bot: opencode-telegram start --daemon
3. Send any prompt via Telegram bot
4. Error occurs immediately

OS
