ETH Receipt errors in 1.0.0-beta.38

[poserr]

I am (was) using this code to send signed transactions to external node and get the receipt:

                                return this.web3.eth
                                .sendSignedTransaction(rawSigned)
                                .once('transactionHash', console.log)
                                .once('receipt', console.log)
                                .on('error', err => {
                                    reject(err);
                                });

After updating to 1.0.0-beta.38 I started to get this error:

web3-core-helpers.umd.js:88 Uncaught (in promise) TypeError: Cannot read property 'blockNumber' of null
    at Object.outputTransactionFormatter (web3-core-helpers.umd.js:88)
    at GetTransactionReceiptMethod.afterExecution (web3-core-method.umd.js:491)
    at GetTransactionReceiptMethod._callee$ (web3-core-method.umd.js:449)

    at _next (asyncToGenerator.js:25)

somehow outputTransactionFormatter is being called immediately after transactionHash event with empty "receipt" object.

I have to add that transaction itself is created and pushed to ropsten network successfully.

transactionHash event is also immediately fired.

[poserr]

It looks similar to #2246 and I am using WebSocket provider.

The error is thrown immediately after sendSignedTransaction method call, right after transactionHash event

got already fixed in PR: #2248 I will prepare a release now and publish it.
