Describe the bug

Note: We've encountered this bug in our CI pipeline run on a fairly standard GitHub Actions setup (cf. https://github.com/mangrovedao/mangrove-bots/actions/runs/5276245102/jobs/9571216174, if interested).

Bug

forge script fails when deploying to (a local fork of) Polygon mainnet - seemingly due to https://gasstation-mainnet.matic.network/v2 being used to get gas-fees (I assume due to the long-standing Polygon/ethers.js fee-issue, cf ethers-io/ethers.js#2828). This gasstation has recently (this week) stopped being available.

We are ourselves in the middle of switching over to https://gasstation.polygon.technology/v2 for gas-fee estimation for Polygon mainnet.

Without having dug deeply in the underlying code for forge, I assume that forge may need to do something similar.

PS adding the --legacy option to the forge script command does seem to alleviate the problem, so for now, we're using that to unblock our CI pipelines.
