[DEVEL] VRF AddConsumer is failing

Description
I am trying to add a consumer to my VRF Chainlink Subscription using my smart contract, but every time i get an error stating that it cannot estimate gas.

Your Environment
Hardhat + Windows + Solidity

Basic Information
The error once i try to call COORDINATOR.addConsumer() function is as follows:

Error: ERROR processing D:\projects\lottery\deploy\01-deploy-lotteryOneWinner.js:
Error: cannot estimate gas; transaction may fail or may require manual gas limit [ See: https://links.ethers.org/v5-errors-UNPREDICTABLE_GAS_LIMIT ] (reason="execution reverted", method="estimateGas", transaction={"from":"0xAc5BB2Ee24FC60fE729BAF80FEEd8025c1D298Ef","data":"0x61014060405260

Steps to Reproduce

You can check out my contract here (vrfCoordinator is hardcoded for the polygon mumbai network):

https://mumbai.polygonscan.com/address/0xa9632B5b79769e1E5Aea0A891804055E9848E2AB#writeContract

The addConsumer function is meant to add the consumer, but it does not work.

Start by reproducing the call to COORDINATOR.addConsumer() from the linked Polygon Mumbai contract using the reported Hardhat setup and the available gas-estimation error. Compare the contract and coordinator configuration against the expected consumer-registration flow; done means identifying the revert cause and confirming that addConsumer succeeds.
