PRIVATE_KEY not needed for simulation

[aelmanaa]

Hi team,

ISSUE:

1. In a terminal, clone the functions-hardhat-starter-kit repository and change to the functions-hardhat-starter-kit directory.

   git clone https://github.com/smartcontractkit/functions-hardhat-starter-kit && \
   cd functions-hardhat-starter-kit

2. Run npm install to install the dependencies.

   npm install

3. Run npx hardhat functions-simulate-script

   npx hardhat functions-simulate-script

--> Error:

 Please set the encryption password by running: npx env-enc set-pw
 ...
 Set the PRIVATE_KEY environment variable with your EVM wallet private key

Problem:

Users shouldn't be required to provide a PRIVATE_KEY to simulate a request.
