the transaction created by libs can't send to cardano-node

[SebastienGllmt]

Thank you for your interest in our project. The error message isn't helpful and so this is partially a guess, but cardano-node has historically deviated from the specification for its transaction signing algortihm. It could very well be a bug in our library, or it could be an issue with cardano-node

Has the codes been tested for integration?

fixed it,with prefix '18b1'

@islishude Try upgrading to Cardano-cli 1.15.0 or higher and maybe it will work (without the magic prefix)
