Post index ${index} not found; ${username} has ${snapshot.po

Error message

Post index ${index} not found; ${username} has ${snapshot.posts.length} recent posts.

What it means

pickPost throws EmptyResultError with this message when the requested 1-based index does not exist in a non-empty snapshot. The library resolved the profile feed successfully and found posts, but fewer than index of them, so the requested post cannot be selected.

Solutions

1. Run the listing/read command first to see how many posts exist, then choose a valid --index
2. Clamp index to snapshot.posts.length in your wrapper before calling the API
3. Re-check whether pinned/deleted posts changed the visible count since your last run

Example fix

// before: arbitrary index
await setInstagramPostLike(page, { username: 'user', index: 10 }, true);
// after: clamp to available posts
const maxIndex = snapshot.posts.length;
await setInstagramPostLike(page, { username: 'user', index: Math.min(10, maxIndex) }, true);

const count = (await readPostSnapshot(page, username, 1, command)).posts.length;
if (!Number.isInteger(index) || index < 1 || index > count) throw new Error(`--index must be 1..${count}`);

function isValidIndex(index, posts) { return Number.isInteger(index) && index >= 1 && index <= posts.length; }

try { await setInstagramPostLike(page, kwargs, true); } catch (e) { if (/Post index .* not found/.test(e.message)) { console.warn(`Index out of range; ${e.message}`); } else throw e; }

When it happens

Trigger: Calling instagram like/unlike with --index greater than the number of visible posts — e.g. --index 10 on a profile showing 6 posts — or a feed that re-rendered between snapshot reads and now shows fewer posts.

Common situations: Assuming a full page of 12 posts on a low-activity account; indices captured from an earlier session when the account had more posts; deleted posts or reordering (pinned posts) shrinking the visible list.
