Is there any way to bypass this error message?
error code: -26
error message:
mempool min fee not met, 15000 < 17463
Also ensure the transaction fee rate at least 1 sat/vbyte, because AFAIK Bitcoin Core also shows similar error.
But it's also possible other node simply can't include the transaction on their mempool, since default mempool size is 300MB while total size of all unconfirmed transaction is 300MB. But i can't confirm this my node,
https://blockchair.com/bitcoin,
https://mempool.space/ and
https://jochen-hoenicke.de/queue shows different mempool size with big difference.
