Daytona command failed (exit ) ` : ""}

Error message

Daytona ${label} command failed (exit ${result.exitCode ?? "unknown"})${detail ? `: ${detail}` : ""}

What it means

Exit-code check in assertSandboxCommandOk: a command executed inside the Daytona sandbox (e.g. tar/cleanup helpers around sync) returned a non-zero exit code (or timing out maps to non-zero), and its trimmed stdout/stderr is appended as detail. This converts a failed sandbox-side helper step into an aborting error for the enclosing sync operation.

Solutions

1. Inspect the exit code and detail in the message; fix the remote command and retry.
