Thanks. My linux bitcoind server is almost done syncing, will look into 0.19.1 when it finishes. My question though would be how do mining pools do this?

Most of them probably don't rely completely on Bitcoin Core and builds the block using their own implementation. Most mining pool don't use GBT but stratum instead.

Unless you're able to see how the pool functions, you probably won't know if the problem exists for them and what their remedy is. Since the error exists due to the fact that they expect the coinbase flags, they can just add it at the end before feeding it to the miners.

When you say add it at the end, you mean compile it back in?
