  <a href="https://wso2.org/jira/browse/IDENTITY-4633" rel="nofollow">https://wso2.org/jira/browse/IDENTITY-4633</a></p>
  
  <p>Any solutions for solving this issue.., 
  We tried to temperorly solve this issue by editing sqlscripts.java file by downloading it from github, compiled it and tried to pack in same jar file (using winzip, as jar files are zip finally).</p>
  
  <p>As part of the change we had removed TOKEN_SCOPE column from relevant sql query, but still error in log describes 'invalid column TOKEN_SCOPE'
  Kindly suggest to make any further changes or share me the jar file.
  I am using wso2 identity server v5.1.0</p>
  
  <p>Thanks.</p>
