I'm running Nethermind locally (http://localhost:8545) but I'm getting the following error:

/home/emlautarom1/Development/Nethermind/low-gas-fee-estimation/node_modules/@ethersproject/logger/lib/index.js:238
        var error = new Error(message);
                    ^

Instead of using this script, could I use the Nethermind.Cli like this?

eth.estimateGas({from: "0x9d055dd23de15114ec95921208c741873ede8558", to: "0xe74bc1c4c27284ab7dbcf55f71fcc04b832fc32c", data: "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"})

I am not that familiar with Nethermind itself but I am guessing you should be able to use the CLI as well. Make sure you install ethers v5.0.3, I have not tested the script with other versions.
