A Set Variable component saves the current payload to a variable named 'images.' What is the DataWeave expression to access the images variable?

The DataWeave expression to access the variable named 'images' that is set by the Set Variable component is represented by #[vars.images]. This is because in MuleSoft, any variable that is defined or modified in the flow and specifically set using a Set Variable component falls under the 'vars' scope, which is a shorthand for flow variables.

When you declare a variable in a Mule application using the Set Variable component, it is stored in the flow variable context. This allows you to access it throughout the flow using the appropriate syntax.

In this case, the prefix 'vars' indicates that you want to reference a variable from the flow variable scope. Therefore, #[vars.images] accurately retrieves the contents of the 'images' variable that has been set earlier in the flow.

Other DataWeave expressions presented do not refer correctly to the flow variable context or point to the correct payload scope, which is why they would not yield the expected results when attempting to access the 'images' variable.
