WalkthroughError handling enhancements added to the social share button module. Multiple operations—container resolution, share URL computation, window navigation, and clipboard operations—are now wrapped in try/catch blocks with console error logging to prevent unhandled exceptions and provide better error visibility.

89-102:⚠️ Potential issue | 🟠 MajorAbort init when container lookup fails.
The new catch sends invalid selectors down the same silent no-op path as a missing container: no button is mounted, but
createModal()andattachEvents()still run. The React/Preact wrappers instantiate this constructor directly, so this becomes a silent initialization failure instead of a surfaced one. HavecreateButton()signal failure soinit()can stop instead of continuing with an unusable instance.🤖 Prompt for AI Agents
Verify each finding against the current code and only fix it if needed. In `@src/social-share-button.js` around lines 89 - 102, createButton() currently swallows invalid container selector errors and continues, causing init() to proceed to createModal() and attachEvents() on an unusable instance; change createButton() to surface failure (either return null/false or rethrow the caught error) when the container lookup fails, and update init() to check the createButton() result and abort initialization (skip createModal() and attachEvents() and propagate/throw the error) if creation failed; references: createButton(), init(), createModal(), attachEvents(), and the class constructor that calls init().

- Around line 413-419: When URL generation or navigation fails in the share
flow, do not let the function continue to the success branch; inside the catch
blocks around this.getShareURL(platform) and the later navigation/open code,
emit the analytics event social_share_error (including the caught error message)
and return immediately to avoid running onShare or emitting social_share_success
or the "No share URL configured" branch; update the catch handlers that
currently log errors to call the analytics emitter (matching the payload shape
used in src/social-share-analytics.js) with event name social_share_error and
then return from the enclosing method instead of falling through.
- Around line 96-97: Replace all bare console.error calls in the catch blocks of
src/social-share-button.js with the library's debug-gated helper
`_debugWarn(message, err)` (or create it if missing) so logging is only emitted
when options.debug is truthy; specifically, change the catch in the DOM
container selector error (current catch around the "DOM manipulation failed:
Invalid container selector" message) and the other listed catch blocks (around
lines 417-418, 428-429, 435-436, 487-493, 531-532) to call `_debugWarn("...
descriptive message ...", error)` instead of console.error, and implement
`_debugWarn` as a private function that checks `options.debug` before calling
console.* to satisfy the `no-console` rule and match the approved pattern.

Replace bare console.error calls with a debug-gated helper.
These catch blocks now write directly to consumers' browser consoles. In this repo that both violates the approved library logging pattern and trips the project's no-console rule; reuse or generalize a single private helper gated by options.debug instead.
Based on learnings: bare console statements in library catch blocks are unacceptable in production, the approved pattern is a debug-gated _debugWarn(message, err) helper, and eslint.config.js already enforces no-console: error.

Do not report social_share_success after a caught share error.
If URL generation or navigation/open throws, the new catches swallow the failure and this method still falls through to either social_share_success or the generic "No share URL configured" branch. That makes the analytics payload incorrect relative to src/social-share-analytics.js:19-75, and onShare can run for a failed share. Emit social_share_error with the caught message and return from the catch path before the success/onShare branch.

@Akshat0125 please update the PR as per CodeRabbit’s review, specifically removing redundant try-catch blocks as makred by coderabbit (e.g., around window.open, window.location, and the outer clipboard wrapper) and replacing all console usage with the _debugWarn pattern. You can refer to the earlier implementation( #99 ) where _debugWarn was introduced—logging should be debug-gated and not use direct console.*. Also, it would be better to open an issue first so the scope is properly documented and tracked, and then align the PR accordingly. @coderabbitai please open an issue outlining error handling improvements and clearly identifying where try-catch is actually necessary. |

Updated issue body (copy-paste into ## Overview
This issue tracks the error handling improvements needed in `src/social-share-button.js`, covering where try-catch blocks are necessary and the correct logging pattern to use.
**Requested by:** `@krishnan05`
**Related PR:** https://github.com/AOSSIE-Org/SocialShareButton/pull/129

## ✅ Try-catch blocks that ARE necessary
### 1. `createButton()` → `document.querySelector()`
`querySelector()` throws a `SyntaxError` when passed an invalid CSS selector string. Since the selector is user-supplied via `options.container`, a try-catch here is appropriate defensive programming.
### 2. `fallbackCopy()` → rename `_err` → `error` and add logging
The existing catch block silently swallows errors. Binding the error variable and logging it through the debug-gated `_debugWarn()` helper is a valid improvement.
---
## ⚠️ Logging pattern
All catch blocks must use the project's established debug-gated helper rather than bare `console.error(...)`, which violates the `no-console` ESLint rule (enforced since issue `#44`).
**Required pattern** (introduced in PR `#99`):
```js
// ✅ Correct — debug-gated, no console pollution in production:
} catch (err) {
this._debugWarn('Descriptive message about what failed', err);
