Could not prepare statement (1 not authorized to use function: random)

Using Query ORDER BY RANDOM() LIMIT 5; Gives the error
Could not prepare statement (1 not authorized to use function: random)

• Is random function supported by chrome websql if yes why I am getting such error?
• Do I need permission from the user to use RANDOM() function if so how do I obtain it?
• I saw an issue over here
• Is this a bug in Chrome?
