Description

As the title says, there is a bug in etherscan data while working with Polygon mainnet or the testnet

I tried this code: https://github.com/shekohex/ethers-etherscan-issue

I expected to see this happen: To have the gas oracle information

Instead, this happened:

Looks like there is a need to handle a new update with the etherscan returned data!

looks like we need to change the types from u64 to f64

do you want to give this a try?

[shekohex]

After narrowing down the issue to just as simple as this Playground it returns the error: "invalid digit found in string", line: 7, column: 31" and this points out to the SafeGasPrice I guess.

Changing these values to be f64 Like here in the updated Playground Solves the issue.

Will open a PR with the quick fix shortly!
