How would I debug an error that only happens on testnet but not locally (with hardhat and/or ganache-cli)

Error: cannot estimate gas; transaction may fail or may require manual gas limit (error={"name":"ProviderError","code":3,"_isProviderError":true,"data":"0x08c379a0000000000000000000000000000000000000000000000000000000000000002000000000000000000000000000000000000000000000000000000000000000034148430000000000000000000000000000000000000000000000000000000000"}, method="estimateGas", transaction={"from":"0x5047d5567a7daD0b30CFc7C60fD4cA25ADAFfBDe","to":"0x62A38f77542Eb227C824495C803FFf677A678ee5","data":"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","accessList":null}, code=UNPREDICTABLE_GAS_LIMIT, version=providers/5.4.5)
