On some occasions - ERROR: Internal : A token must be provided to release a lock

[EstebanCarrasco]

I'm having a problem On some occasions, the action acquire Lock does not return an exit token. Therefore when I try to unblock, the process stays stuck.   Any idea or is it a bug of the product? How do I solve this? I attach my screenshots.

Please can you post sample  code u are using while lock?Also please post screenshot of Lock panel in the System tab.  I hope u are following the standard template code published by Blueprism.

If Acquire Lock does not return a token then it means some one else has the lock.

If i'm not wrong you must be using 'Release Lock' directly. Instead of that create a logic to check if the lock is available & then only release the lock. This will make the process not to get stuck.

Disregard my previous comments...can you check if you are passing a data item for token?
