Friday Fact: Logic Apps Initialize variables action has a max limit of 20 variables

This technical article explains a specific limitation in Azure Logic Apps: the 'Initialize variables' action supports a maximum of 20 variables per single action. It details the error encountered when exceeding this limit and clarifies it's a per-action, not per-workflow, constraint. The article provides practical solutions, recommending the use of objects/arrays, 'Compose' actions for constants, workflow parameters, and splitting initializers for better design and maintainability.
