I sought after to check the submitblock rpc name in regtest however I appear to have some problems with the transactions I attempt to post.

I’ve the next uncooked transactions:

02000000010000000000000000000000000000000000000000000000000000000000000000ffffffff03016900ffffffff0158660c2a010000001976a914a08da9e35ab58e957204703da9d48967ddd1703b88ac00000000 (coinbase tx)

I calculated the txids for all of those tx (byte order already reversed):
6c13bf0a4bf648312d82fa454b2f4ad9a4ead32a805009d5949f981c4cf3bd3b (coinbase txid)

when put so as, I am getting the next merkle root:
5e76726c3a221c7ef39bbbc6d0ca57dd85d320ac13dda01994c517b7c2fc1385

I post the block by way of submitblock. from the merkle root on it looks as if this:

nonetheless, I am getting the next error: bad-txnmrklroot

do I pass over one thing obtrusive right here or is it a bit of extra difficult?

thank you prematurely
