Error message

antigravity copy-code

What it means

EmptyResultError (code 'EMPTY_RESULT') from 'antigravity copy-code': the in-page script found zero Copy buttons associated with code blocks (`btns.length === 0`) or returned nothing, so there is no code text to report. The message names the command ('antigravity copy-code returned no data') with hint 'No code blocks visible.' It reflects page state, not a bug in your arguments.

Solutions

1. Scroll to / render an assistant reply that contains a fenced code block, then re-run.
2. Run `antigravity copy-message` first to confirm assistant content is visible at all.
3. If code blocks exist but have no copy button, the UI changed — update the button-matching selector in audit-extras.js.
4. Verify you are attached to the right conversation/tab.

Example fix

// before
antigravity copy-code 0   // no code blocks on screen

// after
# ensure a reply containing code is rendered, then:
antigravity copy-code 0

// Confirm code blocks exist before invoking copy-code
const codeCount = await page.evaluate("document.querySelectorAll('pre, code').length");
if (!codeCount) throw new Error('No code blocks rendered on screen.');

function hasCodeData(data) {
  return data != null && typeof data === 'object'
    && typeof data.total === 'number' && data.total > 0
    && typeof data.text === 'string';
}

try {
  const rows = await runCmd('antigravity copy-code 0');
} catch (e) {
  if (e.code === 'EMPTY_RESULT') {
    console.error('No code blocks visible — render a reply containing fenced code first.');
  } else throw e;
}

When it happens

Trigger: Running `antigravity copy-code` (with or without an index) when the visible assistant replies contain no code blocks — the scrape finds no copy-code buttons and `if (!data)` throws.

Common situations: The current reply is prose-only with no fenced code; the conversation is empty; code blocks are rendered without the expected copy button in a newer Antigravity version; you are scrolled to a part of the chat without code.
