Testing local bigchaindb node gives Error

I am following bigchaindb Basic usage example from bigchaindb docs. https://docs.bigchaindb.com/projects/js-driver/en/latest/usage.html. I am using following versions : bigchaindb : 2.0 bigchaindb-driver: 4.0.0

Running following code

const driver = require('bigchaindb-driver') const alice = new driver.Ed25519Keypair() const conn = new driver.Connection('http://localhost:9984/api/v1/') const tx = driver.Transaction.makeCreateTransaction( { message: 'Blockchain all the things!' }, null, [ driver.Transaction.makeOutput( driver.Transaction.makeEd25519Condition(alice.publicKey))], alice.publicKey) const txSigned = driver.Transaction.signTransaction(tx, alice.privateKey) console.log(txSigned) conn.postTransactionCommit(txSigned)

I Face following Errors

In node console : { message: 'HTTP Error: Requested page not reachable', status: '500 INTERNAL SERVER ERROR', requestURI: 'http://localhost:9984/api/v1/transactions?mode=commit' }

From bigchaindb server console :

I have the same problem, how do you solve it

[MsalekM]

the same problem, any ideas ?

[getlarge]

@PayResto How do you call makeCreateTransaction method ? I suspect that for @amankakar the null metadata argument might cause some issues, i think i encountered this problem few days ago.

[MsalekM]

@getlarge I don't understand, when I restart the server it works, and it happens again after a few hours i use the example in index page like this

const tx = BigchainDB.Transaction.makeCreateTransaction(
                // Define the asset to store, in this example it is the current temperature
                // (in Celsius) for the city of Berlin.
                { city: 'Berlin, DE', temperature: 22, datetime: new Date().toString() },

                // Metadata contains information about the transaction itself
                // (can be `null` if not needed)
                { what: 'My first BigchainDB transaction' },

                // A transaction needs an output
                [ BigchainDB.Transaction.makeOutput(
                        BigchainDB.Transaction.makeEd25519Condition(alice.publicKey))
                ],
                alice.publicKey
            )

is not a driver problem
