<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This looks like a bug to me, since the string appears to be trying to contain multiple values.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thus, I’m changing the string used to just <span lang="EN" style="font-size:12.0pt;font-family:"Courier New";color:black">
"client_secret_basic"</span> to make the example correct. But I thought I’d point this out in case the example may have been intentional in some manner.<o:p></o:p></p>
