Common Errors
Twitter/X has a 21.3% failure rate across Zernio's platform (17,385 failures out of 81,796 attempts). Here are the most frequent errors and how to fix them:
| Error | What it means | How to fix |
|---|---|---|
| "Tweet text is too long (X characters). Twitter's limit is 280 characters. Note: URLs count as 23 characters." | Exceeds 280 character limit for free accounts | Shorten text or use customContent for Twitter. Remember: URLs = 23 chars, emojis = 2 chars. |
| "X (Twitter) does not allow duplicate tweets" | Same or very similar content was already posted | Modify the text, even slightly. |
| "Rate limit hit. Please wait 10 minutes" | Zernio's velocity limit was triggered | Reduce posting frequency. Space posts at least 4 minutes apart. |
| "Missing tweet.write scope" / "forbidden" | OAuth token lacks required permissions | Reconnect the account with all required scopes. |
| Token expired | OAuth access was revoked or expired | Reconnect the account. Subscribe to the account.disconnected webhook to catch this proactively. |
