Getting error while sending transaction over bigchaindb node

[CruzzRazor]

• bigchaindb-driver version:0.6.2
• bigchaindb server version (bigchaindb -v):2.0.0b9
• Python version:3.7
• Operating System:Ubuntu 18.4

Description

I am referring http://docs.bigchaindb.com/projects/py-driver/en/latest/usage.html
I am getting error while sending transaction over bigchaindb node. saying '''TransportError: (500, '{"message": "Internal Server Error"}\n', {'message': 'Internal Server Error'}, 'http://localhost:9984/api/v1/transactions/')'''

What I Did

in my bigchaindb config file

    "server": {
        "bind": "localhost:9984",
        "loglevel": "info",
        "workers": null
    },
    "wsserver": {
        "scheme": "wss",
        "host": "localhost",
        "port": 433,
        "advertised_scheme": "wss",
        "advertised_host": "secure.bleocean.com",
        "advertised_port": 9985
    },
    "tendermint": {
        "host": "localhost",
        "port": 26657
    },
and so on.....

so my rooturl becomes
bdb_root_url = 'http://localhost:9984'

I followed all steps in above docs link.
now when i am sending the transaction over to a BigchainDB node using following command i am getting error:

sent_creation_tx = bdb.transactions.send_commit(fulfilled_creation_tx)

Error Msg:

I am facing exact similar issue and I have asked about it in https://stackoverflow.com/questions/61580896/getting-error-while-sending-transaction-over-bigchaindb-node

The entire setup was running fine and the docker container had to be restarted post which, it stopped working.

I can't run tenderming unsafe_rest_all - as it would reset my existing data. Any kind help at the earliest will be highly appreciated.
