Error: pattern must be a RegExp

I need to accept a mobile number as input of web-service, but i am facing following issue while validating with Joi framework.

Joi says:

Error: pattern must be a RegExp
    at Object.exports.assert (/home/gaurav/Gaurav-Drive/code/nodejsWorkspace/ragchews/node_modules/joi/node_modules/hoek/lib/index.js:524:11)

    at Module.load (module.js:356:32)
    at Function.Module._load (module.js:312:12)
    at Module.require (module.js:364:17)

for validation:

var userProfileValidation = function(){
    return {
        payload : {
            uid: Joi.string().required().alphanum().length(userConfigs.UID_LENGTH),
            mobile_num: Joi.string().required().regex('^[0-9]*$').length(userConfigs.RMN_LENGTH) //for this guy
        }
    };
}();

I checked the regex on freeformatter and it seems to work fine for atleast some inputs. I don't understand why joi is throwing this error.

Actually, as documented here (link) the Joi framework expects here not a regex pattern, but an actual regex. i.e.: you should use:

Joi.string().required().regex(/^[0-9]*$/) [...]

... instead of:

Joi.string().required().regex('^[0-9]*$') [...]
