Invalid transaction hash

[danionita]

• bigchaindb-coalaip version: 0.0.5

• Python version: Python 3.6.6

• Operating System: 18.04.1 LTS (Bionic Beaver)

• pycoalaip version: 0.0.3

• bigchaindb-driver version: 0.6.1

Description

I was trying to use the bigchaindb-coalaip plugin to register a COALAIP WORK on a BigChainDB instance. However, the transaction generated by the plugin has invalid hash.

What I Did

I ran the following python script.

plugin = Plugin("http://172.20.0.2:9984")
coalaip = CoalaIp(plugin)

user = coalaip.generate_user()

work_data = {'name': 'work1'}
work = coalaip.register_work(work_data, copyright_holder = user)

It threw the following error:

Traceback (most recent call last):
  File "/usr/local/lib/python3.6/dist-packages/coalaip_bigchaindb/plugin.py", line 186, in save
    self.driver.transactions.send(fulfilled_tx)

    method='POST', path=self.path, json=transaction, headers=headers)

    raise exc_cls(response.status_code, text, json)
bigchaindb_driver.exceptions.BadRequest: (400, '{"message":"Invalid transaction (InvalidHash): The transaction\'s id \'549592207864100776fe8fdc58e7fafead2c293424a7b76140640db12b1cf375\' isn\'t equal to the hash of its body, i.e. it\'s not valid.","status":400}\n', {'message': "Invalid transaction (InvalidHash): The transaction's id '549592207864100776fe8fdc58e7fafead2c293424a7b76140640db12b1cf375' isn't equal to the hash of its body, i.e. it's not valid.", 'status': 400})

The above exception was the direct cause of the following exception:

What version of BigchainDB are you using? This package is only supported until bigchaindb~=1.0.1: https://github.com/bigchaindb/pycoalaip-bigchaindb/blob/master/setup.py#L24

[danionita]

Thanks for the quick reply! I am running the latest release of BigchainDB, v2.0.0b7. Are you aware of any plans to support v2 or any alternatives for using COALAIP on BigchainDB v2?

[TimDaub]

I don't know of any plans. Best to ask in gitter: https://gitter.im/bigchaindb/bigchaindb?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge

[danionita]

Thanks, I did. But maybe it's a good idea to mention this compatibility issue somewhere more prominently than inside a .py file which is not even used anymore.
