I'm getting the same issue. When I dig into the error details I'm seeing code: 'UNPREDICTABLE_GAS_LIMIT', returned by the server. Any ideas?

In Theory yes, you could replace await this.bundleExecutorContract.provider.estimateGas( { ...transaction, from: this.executorWallet.address }) With a gas number which you find to be the average of a transaction. It sends gas limit double the number you put in. This is far from optimal to use but it's technically a go around. If you don't want to use static gas, then you'd have to see if you can change the ethers estimation interaction. Or change it with another lib. I haven't found the solution yet but I've had this for a couple hours now so.
