https://community.blueprism.com/t5/Product-Forum/Environment-Locking-Acquire-Lock-action-token-issue/m-p/88884#M39361 Hi, Sanjay. I have a similar problem with locking in v6. The reason for this behavior is unclear. I suppose that this situation occurs when the BP server freezes. It looks like a bug in blue prism.

This is happening only sometimes. otherwise, the input token value is generated as the output. Is this a known issue in v5? Please refer to the attached screenshot for Acquire Lock stage logs during normal behaviour and during the issue.
