Cause

SharePoint Workflow Manager has a limitation of 50 arguments for a 'DynamicActivity'. A workflow is considered a dynamic activity as it can be nested inside of other workflows. Each variable configured in a workflow is considered an argument. Each Nintex Workflow Action that utilizes Nintex Live has two arguments associated with it (input and output).

Resolution

Reduce the amount of Variables and or reduce the amount of Nintex Live actions in the workflow.
