Embark with Ganache - Error: Provider not set or invalid

[piavgh]

Bug Report

Summary

I tried to deploy smart contracts with Embark, and I connect to Ganache. The smart contracts seem to be deployed correctly but there are some error logs that I think I need to report

Current behavior

After embark run, I got these errors:

This is the screenshot when everything is done:

How to reproduce

Setup a normal embark project and connect to Ganache on port 7545. You can see the contracts here https://github.com/tomochain/tomorelayer/tree/master/contracts

Expected behavior

I think it's better that we don't have any error here

If you encounter an error, please create a logfile using the following command and post the output here

$ embark run --nodashboard --logfile log.txt --loglevel trace

Please provide additional information about your system

OS: Ubuntu 18.04 Embark Version: 3.2.7 Node Version: 10.15.0 NPM Version: 6.4.1

Sometimes issues are related to Embark's installation. Can you provide information on how Embark was installed?

There are 2 lines in devDependencies:

"embark": "^4.0.2",
"embarkjs-connector-web3": "^4.0.0",

Then yarn install

Hi @piavgh , thanks for reporting. Could you run again with embark run --nodashboard --loglevel=trace and paste le logs here (mostly the error and it's surrounding). It will be easier to debug that way. Thank you

Hi @piavgh , I just tried testing the repo you linked (https://github.com/tomochain/tomorelayer), and it worked for me. Maybe it's your connection to Ganache that is not done correctly. I see in your setup that you start Ganache on port 7545, but no where in the config you specify that port, could it be you have your own branch or you maybe just forgot?

Also, the last error about EmbarkJSConnectorWeb3 seems to say that you may have an old version of it installed. Try to re-run npm install or npm instal embarkjs-connector-web3 to make sure you have the latest version.

Hi @jrainville , sorry, in blockchain.js I updated it and didn't push to git

  default: {
    enabled: true,
    rpcHost: "localhost", // HTTP-RPC server listening interface (default: "localhost")
    rpcPort: 7545, // HTTP-RPC server listening port (default: 8545)
    rpcCorsDomain: '*',
    wsRPC: true, // Enable the WS-RPC server
    wsOrigins: '*',
    wsHost: "localhost", // WS-RPC server listening interface (default: "localhost")
    wsPort: 7545, // WS-RPC server listening port (default: 8546)
  },

Also, in contracts.js, I updated it:

default: {
    // Blockchain node to deploy the contracts
    deployment: {
      host: "localhost", // Host of the blockchain node
      port: 7545, // Port of the blockchain node
      type: "ws", // Type of connection (ws or rpc),
      accounts: [
        {
          mnemonic: process.env.MNEMONIC,
          addressIndex: 0,
          numAddresses: 8,
          balance: "900000 ether",
        }
      ]
    },

Other than that, nothing is changed compares to my master branch

I also tried to update embarkjs-connector-web3 to latest version (4.0.0) but it didn't work also.

Can you please tell me how did you setup Ganache?

Thank you.

[jrainville]

I tried your latest master with the changes above, and it still worked for me (other than the deployment reverting).

I started Ganache using embark simulator and it gave:

running: ganache-cli -p 7545 -h localhost -l 8000000 -a 10 -e 100 --networkId 1337
Ganache CLI v6.2.3 (ganache-core: 2.3.1)

And then embark run --nodashboard --nobrowser:

I think the revert might be because my account doesn't have funds. Anyway, I don't have the connector error nor web3 error.

I'm using Ganache GUI. Maybe that's the reason why.

I will try using ganache-cli and will let you know
