Curl success, but Internal Server Error when commit transaction

[leejie8008]

• bigchaindb-driver version: 0.6.2
• bigchaindb version: 2.0.0b9
• Python version: 3.6.8
• Operating System: Virtual machine of Ubuntu 16, through Window 10 host

Description

I set up bigchaindb, with python driver and mongodb. Then, I try to run the code from Basic Usage Example, and receive Internal Server Error, but when I run curl http://localhost:9984/api/v1/transactions, it shows {"message": {"asset_id": "Missing required parameter in the JSON body or the post body or the query string"}}, which means that my connection is established.

How can I debug form here?

What I Did

from bigchaindb_driver import BigchainDB
from bigchaindb_driver.crypto import generate_keypair
from time import sleep
from sys import exit

bdb_root_url = 'localhost:9984'
# bdb_root_url = 'http://127.0.0.1:9984'
bdb = BigchainDB(bdb_root_url)

bicycle_asset = {
    'data': {
        'bicycle': {
            'serial_number': 'abcd1234',
            'manufacturer': 'bkfab'
        },
    },
}

bicycle_asset_metadata = {
    'planet': 'earth'
}

alice, bob = generate_keypair(), generate_keypair()

prepared_creation_tx = bdb.transactions.prepare(
    operation='CREATE',
    signers=alice.public_key,
    asset=bicycle_asset,
    metadata=bicycle_asset_metadata
)

fulfilled_creation_tx = bdb.transactions.fulfill(
    prepared_creation_tx,
    private_keys=alice.private_key
)

sent_creation_tx = bdb.transactions.send_commit(fulfilled_creation_tx)

txid = fulfilled_creation_tx['id']

print("tid: " + txid)

asset_id = txid

transfer_asset = {
    'id': asset_id
}

output_index = 0
output = fulfilled_creation_tx['outputs'][output_index]

transfer_input = {
    'fulfillment': output['condition']['details'],
    'fulfills': {
        'output_index': output_index,
        'transaction_id': fulfilled_creation_tx['id']
    },
    'owners_before': output['public_keys']
}

prepared_transfer_tx = bdb.transactions.prepare(
    operation='TRANSFER',
    asset=transfer_asset,
    inputs=transfer_input,
    recipients=bob.public_key,
)

fulfilled_transfer_tx = bdb.transactions.fulfill(
    prepared_transfer_tx,
    private_keys=alice.private_key,
)

sent_transfer_tx = bdb.transactions.send_commit(fulfilled_transfer_tx)

print("Is Bob the owner?",
    sent_transfer_tx['outputs'][0]['public_keys'][0] == bob.public_key)

print("Was Alice the previous owner?",
    fulfilled_transfer_tx['inputs'][0]['owners_before'][0] == alice.public_key)
