Invalid JSON RPC response: undefined

[Ashwin-Kapes]

Every time I try to run a function on embark dashboard I'm getting an error:
"Error: Invalid JSON RPC response: undefined"
PS: Someone told me to install testRPC 3.0 but don't know how to install it.

Can someone help with this, simulator is running in the background and then anytime I call my contract methods in the Embark console, I get Error: Invalid JSON RPC response: undefined

try npm -g install ethereumjs-testrpc@3.0, followed by embark simulator then re-run embark run; it should say TestRPC 3.0 on the dashboard" (screenshot says 2.0)

I already tried that, version 3 of testrpc errors when building, running version 6 which is the latest. Embark doesn't work with the latest build tools?

@Ashwin-Kapes @JohnAntonusMaximus ok at first this looked like an outdated version but seems to be a bug in the 2.6.0.. a fix will be released in 2.6.1 @JohnAntonusMaximus it doesn't matter the version it should work with all the latest geth nodes & simulators. this is a bug specific to the console, thanks for reporting it :)

Awesome, my pleasure. I like this framework much better than Truffle, if it works as expected going to stick to it. Can be of more help as I get familiar with it. My first time firing it up and I couldn't figure out what the issue was, all the RPC ports are mapped correctly in the config.json files.

@Ashwin-Kapes @JohnAntonusMaximus This has now been fixed in Embark 2.6.1 ; Again, thanks for reporting it.

@JohnAntonusMaximus Thanks! It's about to get a major revamp, so any feedback/wishlist is appreciated.

Hi, I'm still getting this error was well. Should this still be happening?

I also reported the issue here https://stackoverflow.com/questions/51033531/ethereum-embark-console-method-calls-all-returning-as-undefined

@EthanWilkins Embark uses web3.js 1.0 , it should be MDBAccount.methods.post("Hello World").send() and MDBService.methods.register().send({gas:900000})
