Same result when I tried with smaller amount of testcoins.

I noticed that the input script might wrong, but I couldn't use validtx, since I always got "terminate called after throwing an instance of 'libbitcoin::end_of_stream’”.

For example, for this transaction:
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

showtx shows:

However, when I retrieve an arbitrary transaction from network:
$ sx fetch-transaction 15d90534f8bc622bf50c60abb74957f85c99979ea51c155c403fcd9dc80ffd88 | sx showtx

hash: 15d90534f8bc622bf50c60abb74957f85c99979ea51c155c403fcd9dc80ffd88
version: 1
locktime: 0
Input:

Why its public key (second part of the script) is shorter than mine?
