Detailed description:
The "USERNAME_NOT_OCCUPIED" error in Telegram occurs when the provided username is not taken by any user, bot, or group within the system. This error indicates that such a username does not exist in the Telegram database.
The reason for this error is that there is no registered account in Telegram with the specified username. This may happen if you're trying to send a message, perform an action with an account, or find a user by a username that does not exist.
To resolve the "USERNAME_NOT_OCCUPIED" issue, follow these steps:
Step 1: Double-check the username you've entered. Make sure there are no typos or errors in the spelling.
Step 2: Ensure that the user or group you are trying to interact with actually exists. They may have recently deleted their account or changed their username.
Step 3: If the username is available and you need to interact with a specific user, try contacting them through other methods, such as their phone number or another available means of communication.
The "USERNAME_NOT_OCCUPIED" error is a result of restrictions within the Telegram API, where the specified username does not exist in the system. To resolve the issue, you need to verify the username or choose an alternative way to interact.
