Workflow not responsive, Error Code 2147467259

asked on October 27, 2023

Happy Friday!

I am facing a strange problem with a Workflow that I have designed and completed. The workflow is supposed to monitor a folder in the Laserfiche Repository. If a document is created, then the workflow will be triggered. The workflow is fine. I validated it and ensured that there are no errors or problems in it. I published and everything was smooth throughout this process; however, it does not get triggered when the condition in the Rule Manager is satisfied.

I created this workflow very recently in October 2023. I have two other workflows that are exact replica of this workflow, but were created before 2020. All of the three workflow are the same, they just deal with different document types and different folders in the repository. The two workflows that were created before 2020 work as expected. The workflow that I created in October 2023 does not work.

We went through an upgrade in late 2019, but the second workflow runs fine and it is exact replica of this workflow it only deals with a different document type and different folder. The Admin account we use to connect to the repository have the required privileges.

I noticed in my troubleshooting that the following error keeps repeating whenever I run a test. Not sure if this is related, but I would appreciate it if someone helps me or guide me on what to do as I am running out of options. Thank you.
