SharePoint Designer 2013 Workflow error :Microsoft.Workflow.Client.ActivityValidationException: Workflow XAML failed validation due to the following errors: Activity 'someXActivity' has 58 arguments, which exceeds the maximum number of arguments per activity (50).

Hi Guys,

[Update: You can achieve this solution using powershell as well, please refer the link provided at bottom of this post]

Recently I got this workflow error while working with the SharePoint designer workflows in 2013. The error is about the creation of workflow variables/arguments more than 50 in number. By default max variables/arguments allowed in workflow is 50. If we create more than this, we encounter with the following error while publishing the workflow.

“Microsoft.Workflow.Client.ActivityValidationException: Workflow XAML failed validation due to the following errors: Activity “SomeXActivity” has 58 arguments, which exceeds the maximum number of arguments per activity (50).”

The resolution is like this:

Change the default settings of the workflow variable limit in the Workflow Manager table as follows.

Go to SQL where your Workflow Manager Db is stored and set these.

DataBase : WFResourceManagementDB

Table : WorkflowServiceConfig

Rows :  

WorkflowServiceMaxVariablesPerActivity  :   set it to required value and  WorkflowServiceMaxArgumentsPerActivity  : set it to required value.

like this

UPDATE :

You can also set these configurations using power shell Set-WFServiceConfiguration command, please refer below msdn link for more details :
