Bug when entering username with @ symbol

[AbhayJha24]

Issue Description

When some username is entered with @ symbol (For example @myusername) this error comes on the UI

Undefined is not an object (evaluating 'n.data')

Suggested fixes

• Types must be checked before reading properties like data on objects being created from end user input to prevent edge cases like this

• Secondly error texts like these must be logged in the browser console and a user friendly error message should be provided to the end user

GitHub usernames cannot include the @ symbol. According to GitHub’s username policy, usernames may only contain alphanumeric characters or single hyphens and cannot begin or end with a hyphen.
Because @myusername is not a valid GitHub username, this input is considered invalid and is not supported by the application.

@AykutSarac, kindly close this issue as the input is not a valid GitHub username.
