Estimate gas failing - need to have FROM - UnhandledPromiseRejectionWarning: Error: Returned error: execution reverted

[stefek99]

I'm using this as a base: https://blog.infura.io/deploying-smart-contracts-managing-transactions-ethereum/?utm_source=social&utm_medium=facebook&utm_campaign=Tutorials

demo-eth-tx/standard-transactions/web3/call.js

Line 30 in c63a4d6

gas: await tx.estimateGas(),

From the docs: https://web3js.readthedocs.io/en/v1.3.1/web3-eth-contract.html#methods-mymethod-estimategas

Will call to estimate the gas a method execution will take when executed in the EVM. The estimation can differ from the actual gas used when later sending a transaction, as the state of the smart contract can be different at that time. Note: You must specify a from address otherwise you may experience odd behavior.

(emphasis mine)

In my code I had to add {from: process.env.ETH_ADDRESS } and now it works.
