Raw transaction with multiple outputs

[darosior]

Hi,

After achieved the serialization of a raw (non-segwit) transaction with just one input and one output, I tried with multiple inputs and outputs. I managed to have it working with multiple inputs but I can't figure out how to just add another ouput (for change) without getting

Code:

{'code': -26, 'message': '64: scriptpubkey'}

Here is my transaction serialized and decoded in a JSON-like way :

Code:

b'0100000002ee70fec3a5b90501e2e0074e21f6104b4ea4aceadc9250edc5f527250cc14148000000006b483045022100d52f6f23e0413003a2859892c33215f95475fa229e5bf7e42ce045f38c16eed902205a318926c3d9fac231fce274d82a7d84cf43acfeb71e43672ae213faf72a956301210388d662be197297bb54ad9927dee599f5b6731fbbb1da5c6c007fdb377054d2ffffffffffd8b15aa873de6a5f6ea0ec620083cff1bc5776130955ff44414f833500d5ac6a000000006a47304402207fed467bef68953c903d0f77f92c95e84bf2cf414936110ab89898526e095588022069f49e015aae8aff0f2e38275ca809c1b3bb2cfc48c6be47a6b0fec403ab6ba301210388d662be197297bb54ad9927dee599f5b6731fbbb1da5c6c007fdb377054d2ffffffffff02a0860100000000001876a9c0123db6acc268de513acdbbba06a2ebacb6d56d88ac905f0100000000001876a9c0123db6acc268de513acdbbba06a2ebacb6d56d88ac00000000'

I first thought that it was because my change address was the same as the receiver, but even with changing it it did not work :

Code:

I can't figure out what's wrong.

Thank you by advance,

Your scriptPubKey's are incorrect. You are missing the length specifier for the hashes in the scriptPubKey. Your scriptPubKey's should be 76a914c0123db6acc268de513acdbbba06a2ebacb6d56d88ac and 76a914c0123db6acc268de513acdbbba06a2ebacb6d56d88ac. You will need to adjust your transaction accordingly.
