Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'zod' imported from /[...]/@zed-industries/claude-agent-acp/node_modules/@agentclientprotocol/sdk/dist/acp.js

I have not tried sled with claude-code-acp, so not sure if this issue is specific to claude-agent-acp.
I patched sled to use claude-agent-acp. When I try to send something to it, I get the following error in the log:

I worked around it by manually installing zod in the globally installed @zed-industries/claude-agent-acp. Wouldn't this work better if @zed-industries/claude-agent-acp was a dependency (or peer dep?) of sled?

Also it would be nice if errors like could not execute claude-code-acp and "cannot find package" were sent back to the user instead of just showing in the logs.
