  1. In a command window, navigate to PI\adm.

  2. Type:pilistupd –qs piaflink.

  3. Look for the number of pending events. The -19501 error in general can happen if a user attempts to edit a module that was recently created but didn’t get created in PI AF. A retry will definitely fix that issue.
