title: LinkedIn API says access token maximum 255 characters
body: <p>I have a web application and it can successfully obtain access tokens from LinkedIn's API with the token's length equals to 350 characters, but when I am using the obtained access token to request data from LinkedIn, LinkedIn API now throws me an error like this:</p>
  
  <blockquote>
    <p>Access Token is too long (maximum is 255 characters)</p>
  </blockquote>
  
  <p>The web application has been working well for many years and this error only happens recently, is there any change LinkedIn made that I am not aware of?</p>
