missing functions

[sweebee]

I'm using 5.1.2 and i get the following error when redirecting after the oauth login:

Call to undefined method League\OAuth2\Client\Provider\LinkedInResourceOwner::getLocation()

I've added this function and then I get the following error:

Call to undefined method League\OAuth2\Client\Provider\LinkedInResourceOwner::getDescription()

after that:

Call to undefined method League\OAuth2\Client\Provider\LinkedInResourceOwner::getSummary()

And then it works. Is there something wrong?
