Issue publishing Plumsail workflows only

We are looking to purchase some products, but this does not bode well.

I get the error below when trying to publish any workflow with a plumsail action in it. Other Sharepoint Designer workflows publish without errors. I have uploaded the WSP, activated the solution, activated the solution on the site, configured the username and password. Yesterday I tested a site creation workflow and it worked fine. Today that workflow will no longer publish and neither will any others with plumsail steps. Removing the plumsail step and the same workflow will publish just fine. I tried deactivating the site feature to see if re-activating it would work, but deactivating also throws an error.

Microsoft.Workflow.Client.ActivityValidationException: Workflow XAML failed validation due to the following errors:
Cannot create unknown type ‘{clr-namespace:Plumsail.ActionsPack}StringLength’. HTTP headers received from the server - ActivityId: 2f8a6f9a-7e67-4188-bab8-05db20e36e5f. NodeId: . Scope: . Client ActivityId : 1026729d-300f-2000-4500-9fa99b601521. —> System.Net.WebException: The remote server returned an error: (400) Bad Request.
at Microsoft.Workflow.Common.AsyncResult.End[TAs

Note that I have found this post and it has nothing to do with site templates. This happens on even the simplest of workflows (check string length).
Cannot instantiate a site template links to plumsail.com/blog/2015/01/deplo … more-16178

It also has nothing to do with another post about running a powershell script to reconnect the workflow manager, because that issue affects all SPD workflows and my issue is only with workflows that include Plumsail steps.

Please help.

Hello Dominic,

Please write us at [email protected], I think we can setup screen sharing session to resolve the issue.

I´m receiving the same issue on Plumsail Workflows… After installing the Licence. I also did some SharePoint Designer Clear Cache, and reinstalling and upgrade Plumsail Workflow Actions Pack. Unfortunately receiving every time this Error Message:

Microsoft.Workflow.Client.ActivityValidationException: Workflow XAML failed validation due to the following errors:
Cannot create unknown type ‘{clr-namespace:Plumsail.ActionsPack}ActivateFeature’. Vom Server wurden HTTP-Header empfangen

Please help!
Thanks
Andre

Hello,

Could you please try to reactivate Workflow Actions Pack feature and try to re-publish the workflow? ​

You may need to use -Force key for reactivation. Please check out Enable-SPFeature documentation​.
