My .on('Confirmation', {} => ) callback is not called after the above error is thrown. Looks like an error in web3core when sendSignedTransaction is called.

@0x-genesys Thanks for submitting this issue!

Which provider are you using?

[0x-genesys]

Thanks for your prompt response @nivida . I am using HttpProvider , with an infura url:

web3 = new Web3(new Web3.providers.HttpProvider("https://ropsten.infura.io/v3/XXX"));

[0x-genesys]

Oh so issue was in 'receipt' , not 'confirmed'. Once the PR is merged, do I need to re-install node_modules?

[nivida]

@0x-genesys Nope anything is fine :-)
I had to update the afterExecution method of the GetTransactionReceiptMethod class. I didn't handle the case if the method is returning null.

[0x-genesys]

when can the response from the RPC be null?

[nivida]

As described here, will the eth_getTransactionReceipt JSON-RPC method return the value null when no receipt was found.

[0x-genesys]

Im still facing the error. Tried running:

rm -rf node_modules && npm i

@nivida am I missing something?

[akeem]

@nivida I'm not sure if it is helpful, but I am experiencing a similar behavior, is it possible that one of the other calls to outputTransactionFormatter is being passed null?
