Could not find the like control on ${post.code}

Error message

Could not find the like control on ${post.code}

What it means

After selecting the post, the library runs buildToggleLikeJs up to 5 times (sleeping 1s between attempts) to locate the post's like control in the page. This throw fires when all 5 attempts return click.found === false, meaning the like button/selector could not be found at all — usually because the page is not showing the post view the script expects.

Solutions

  1. Open the post in the automated browser and confirm it is not showing a login prompt; re-authenticate if needed
  2. Set the browser/interface language to English
  3. Retry later — temporary Instagram UI experiments can hide the control
  4. Update the library/buildToggleLikeJs selectors to match the current DOM

Example fix

null
Defensive patterns

Strategy: try-catch

Validate before calling

// pre-check that the post view is interactive, not a login wall
const bodyText = await page.evaluate(() => document.body.innerText);
if (/log in|sign up/i.test(bodyText.slice(0, 500))) throw new Error('login wall detected; re-authenticate first');

Type guard

function likeControlVisible(page) { return page.evaluate(() => !!document.querySelector('svg[aria-label="Like"], button[aria-label="Like"]')); }

Try / catch

try { await setInstagramPostLike(page, kwargs, true); } catch (e) { if (/Could not find the like control/.test(e.message)) { /* check login state & language, then retry once */ await ensureLoggedIn(page); return setInstagramPostLike(page, kwargs, true); } throw e; }

Prevention

When it happens

Trigger: Instagram showing a login wall or signup modal instead of the post; non-English interface language changing aria-labels/selectors the script matches on; the post detail view failing to open; DOM structure changes from Instagram updates.

Common situations: Expired or logged-out sessions hitting the login prompt; browsers set to a non-English locale; headless environment where the post modal never renders; recently changed Instagram DOM breaking selectors.
