Error in Sync Workflow

Posted on by Community Member

On update of a service activity a sync workflow is triggered and updates the same SA.
This update triggers a second sync workflow where a custom workflow step is added. During the call of this custom step

an error is thrown and process breaks. The error is thrown before it hits any code in the custom step, and all bling bling is stripped out of it (no params etc)
But still the error is thrown.

Sync workflow failed with error message - Unhandled Exception: Microsoft.Crm.Workflow.Services.InvalidCustomActivityExecutionException: Unexpected exception from plug-in (Execute): MyCustomStep: System.AggregateException: One or more errors occurred.
at System.Activities.WorkflowApplication.Invoke(Activity activity, IDictionary`2 inputs, WorkflowInstanceExtensionManager extensions, TimeSpan timeout)
at System.Activities.WorkflowInvoker.Invoke(Activity workflow, IDictionary`2 inputs, TimeSpan timeout, WorkflowInstanceExtensionManager extensions)
at Microsoft.Crm.Workflow.SynchronousRuntime.SynchronousWorkflowActivityHost.ExecuteWorkflowUsingInvoker(Activity workflow, ICommonWorkflowContext context)
at Microsoft.Crm.Workflow.SynchronousRuntime.SynchronousWorkflowActivityHost.StartWorkflow(WorkflowActivationData activationData, ICommonWorkflowContext context)
, error code - -2147220891

Does anybody know where this error is coming from? (in the error I only replace the real step name with 'MyCustomStep')

RE: Error in Sync Workflow

Thanks for all the replies, but the problem was caused by dll version.

The solution was build with nuget package

<package id="Microsoft.CrmSdk.CoreAssemblies" version="8.2.0.2" targetFramework="net452" />

<package id="Microsoft.CrmSdk.Workflow" version="8.2.0.2" targetFramework="net452" />

But the dll version was 8.0. After forcing the solution to compile with 8.2 dll's problem is solved

RE: Error in Sync Workflow

I have seen the same error when the workflow activity (plugin) isn't setup properly. I would agree with saadzag that you need to make sure you are not in an infinite loop, but if you are not ever even hitting the code in your workflow activity then the issue comes before the loop could start. I would check the following things.

1. If your input parameters are set to "RequiredArgument" make sure that they are getting set.

2. Make sure it follows the proper setup as shown below (there are various ways this could look but here is what I use with or without the "RequiredArgument" attribute)

public class SomeCustomAction : CodeActivity

{

[RequiredArgument]

[Input("Input Data")]

public InArgument<string> InputData { get; set; }

[Output("Output Data")]

public OutArgument<string> OutputData { get; set; }

protected override void Execute(CodeActivityContext executionContext)

{

}

}

3. If all is still good create a new workflow that just calls the workflow activity and on the first line of the Execute method throw an InvalidPluginExecutionException with a message to let you know it at least is calling your workflow activity.

If none of that works you can look into the dll and make sure you have all ILMerged in all dependent resources I use jetbrains dotPeek to look into mine but there are lots of tools out there, If you are still stuck we can look into other options.

Good luck.

RE: Error in Sync Workflow

Hello,

Verify that there is not a loop in execution.

because you have a sync workflow triggered on update, and as you said, it updates the same record.
