Unexpected result from reddit subreddit-info: ${JSON.stringi

Error message

Unexpected result from reddit subreddit-info: ${JSON.stringify(result)}

What it means

CommandExecutionError thrown as a defensive fallthrough when the browser-evaluated result has an unrecognized 'kind' (or result itself is null/undefined). All known kinds (missing/http/malformed/exception/ok) are handled above, so this indicates an unexpected runtime contract violation between the page.evaluate payload and the Node handler.

Solutions

1. Retry the command — a transient page navigation can make evaluate return undefined
2. Ensure a single consistent version of the library is installed (no mixed patched copies) and reinstall if in doubt
3. Report the printed JSON.stringify(result) payload in a bug report — it shows exactly what unexpected shape came back
4. Avoid interfering with the browser window while the command runs so the page is not navigated away mid-evaluation

// run a smoke invocation first and assert a known kind is returned
const probe = await cli.redditSubredditInfo('python');
if (!probe) throw new Error('evaluate returned undefined; environment broken');

function isUnexpectedResultErr(e){ return e instanceof Error && e.message.startsWith('Unexpected result from reddit subreddit-info:'); }

try { await cli.redditSubredditInfo(name); }
catch (e) {
  if (e.message.startsWith('Unexpected result from reddit subreddit-info:')) {
    reportBug(e.message); // message embeds JSON.stringify(result)
    return null;
  }
  throw e;
}

When it happens

Trigger: result is undefined or null (evaluate returned nothing, page navigated during evaluation), or a future/unknown kind value appears after a library version mismatch between the browser snippet and the Node-side handler.

Common situations: Page context destroyed mid-evaluate so evaluate resolves undefined; running a mixed/patched version of the library where the browser snippet returns new kinds the Node handler does not know; serialization dropping the object.
