I’m having a problem trying to generate blocks for Regtest. I get always an error:
ERROR: AcceptBlock: bad-cb-height, block height mismatch in coinbase
The height of the block I’m trying to mine is 1. The height is less than 500, which is the minimum block in Regtest for which BIP34 is enabled, so I don’t understand why the height is a problem. Anyway, the Coinbase transaction I’m using is:
02000000010000000000000000000000000000000000000000000000000000000000000000ffffffff3f01013c8cb3d83abd14588177040029eb9bf1bf952f1f43af61e6df03578d5e3bb261a8e2a4bb1bb2da4bc180d3fc67bd1c73aac0575e280239c2f30dc3acb0000000000100f2052a010000001976a914bf01aa10263be4a8f6cabbdd60a74c7544e48d2a88ac00000000

I don’t see what is the problem with the height value. Someone knows? Thanks
