can you try this ?

curl --location --request POST 'http://127.0.0.1:9933' \
--header 'Content-Type: application/json' \
--data-raw '{

9933 is not a port that is open. I'm running the docker with the rpc.

PORT     STATE SERVICE
631/tcp  open  ipp
3000/tcp open  ppp
3001/tcp open  nessus
5432/tcp open  postgresql
9944/tcp open  unknown

you can test it with websocket here.

Like so:

So this may not be a bug with bodhi.js. @xlc @zjb0807

[ntduan]

Maybe your contract didn't deploy successfully?

[zjb0807]

How can I reproduce the error?

[zjb0807]

If you start node with -levm=debug, you can show me the logs.

[gluneau]

I found the error, I was not using the smart contract address to interact, I was using the returned transaction hash.
