When calling a method that uses a local variable twice, I'm getting this error.

Example smartpy link. In this linked code I added a new method test_string_of_nat2 which triggers this behavior.

How should this type of function be called if it's needed more than once within the same entry point?

You can use the sp.private_lambda decorator.

  • Thanks! That worked for this example. Though, when using it on an off_chain_view I'm getting the error Missing private variable string_of_nat Is it not possible to use within off_chain_views? What could I do if I want to use them here? smartpy.io/…
