web3.eth.estimateGas throws Error

[Deleted user]

Code snippet for web3 creation is as follows:

web3 = createAlchemyWeb3('https://eth-goerli.alchemyapi.io/v2/-Dm....your...key')

Error is thrown from the estimateGas call as follows:

web3.eth.estimateGas({ data, to, from, value })

Error is:

Node error: {"code":-32000,"message":"invalid opcode: opcode 0xdb not defined"}
at Function.validate (web3-providers.umd.js:112)

Version:
"@alch/alchemy-web3": "^0.1.18"

This kind of error does not happen when using the standard web3 with the same code and environment (browser with Metamask)

I've self found out the crash root cause that is because the input arg of to is accidentally NULL.
This happened only for when using Alchemy web3 version 0.1.18 which is based on a very old version of web3.js of 1.0.0-beta.55. I don't know why Alchemy has grabbed this obsolete version despite the latest release is just several months ago.
Indeed, with the above version combination, the contract address retrieval via contract instance is always returned NULL. Code snippet is as follows:

someContractInstance._address

Hi, so sorry that we are just getting to this issue now! We have since updated our dependencies and this should no longer be an issue.
