No workspace selected

Error message

No workspace selected

What it means

signDebugRequest in MonacoDebugger.svelte signs debugger code via /api/w/{workspace}/debug/sign, but it requires an active workspace context. When the `workspace` variable is empty the request cannot even be built, so it throws 'No workspace selected'.

Solutions

1. Select a workspace before starting a debug session
2. Wait for the workspace store to hydrate (guard the debug button on a non-empty workspace)
3. Route to a workspace-scoped URL so `workspace` is defined when the debugger mounts

Example fix

// before
await signDebugRequest(code, lang)
// after
if (!workspace) {
  sendUserToast('Select a workspace before debugging', true)
  return
}
await signDebugRequest(code, lang)

if (!workspace) { sendUserToast('Select a workspace first', true); return }
await startDebugging()

function hasWorkspace(w: string | undefined | null): w is string { return typeof w === 'string' && w.length > 0 }

try { await startDebugging() } catch (e) { if (e.message === 'No workspace selected') { sendUserToast('Select a workspace first', true) } else { throw e } }

When it happens

Trigger: startDebugging is invoked from the Monaco debugger while no workspace is selected — e.g. the debugger is opened in a context (instance-level page, stale store) where the workspace store has not been populated.

Common situations: Opening the debugger before selecting a workspace; workspace store not yet hydrated on first render; deep link into the debugger without a workspace path segment.
