Error on 'npm start'

I'm getting errors when I run npm start:

[danforbes]

Hi, Kris - thanks for checking out this repo! I think you may be experiencing this problem because you either did not run the npm install command or it did not succeed. From the logs you provided, I can tell that the error is occurring when your Solidity contracts are being compiled, and in particular the error is that the compiler is not able to locate the Chainlink client smart contract dependencies; these dependencies should be pulled down when you run npm install. The only way I am able to reproduce this error is by trying to start the project without installing the dependencies first.

[krisc]

Ah, I think that was it haha. Maybe that first step in 'Usage' can be in the 'Dependencies' section to avoid ambiguity? Just an idea.

[krisc]

Hmm, actually, it might be something else. I ran npm i and still get the same error. I did notice though that the Ganache window (after creating the new Workspace) hangs on the loading screen (the Ganache logo with spinning circle thing).

Running Ganache on command line, I notice this warning:

(node:16058) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 2 server-started listeners added. Use emitter.setMaxListeners() to increase limit

[danforbes]

Hm, I am not sure about the problems with Ganache, but running npm i should take care of the errors you shared above. Can you share the output you're getting after running npm i? Whether or not Ganache is running shouldn't impact whether or not you can compile the contracts, which is what the error you shared above is telling me.

[krisc]

hey, I appreciate your taking the time to help me with this!

So after completing npm i, I get this when I run npm start with no Ganache running:

Totally happy to help and really appreciate the same from you :grin: The error you shared above makes perfect sense if Ganache is not running. What is happening is that the contracts compiled successfully and then they are attempting to be deployed to the local Ganache network. Since that is not running, you're getting this error: Something went wrong while attempting to connect to the network. Check your network configuration. I don't really have any experience with the Ganache CLI and the GUI has always "just worked" for me :persevere:

[krisc]

At the workshop at the brewery, I noticed that the Ganache GUI you were using was different than the one I was using, and realized I was using an old version (which didn't have that workspace setup on startup). So I upgraded to the version you were using, but I may just try the CLI for now.

[danforbes]

Don't forget to get it to listen on all interfaces! (0.0.0.0)

[krisc]

running this to start ganache-cli:

ganache-cli -h 0.0.0.0 -p 7545

looks like it compiled and migrated, but npm start still giving an error. looks like it's docker related: https://gist.github.com/krisc/8da0dae2cdac03e1c39bc410a7083783

[krisc]

Not sure if I should do this, but maybe this is helpful. So I ran these series of commands:

ganache-cli -h 0.0.0.0 -p 7545
sudo dockerd
sudo npm start

And it went a little further along, but still got an error: https://gist.github.com/krisc/fe448b8bbe4cb3dc95fd57a7aef64566

[leovigna]

Are you running on Mac or Linux? This seems to point to HOST_IP env var not getting set. WARNING: The HOST_IP variable is not set. Defaulting to a blank string. This seems be a problem on Mac as the command ip will not work. This bug is particularly pervasive as it only shows as a warning, but the actual effect is that the Chainlink node is unable to connect to Ganache. If you are a Mac user, I'd suggest replacing in package.json: HOST_IP=$(ip -4 addr show docker0 | grep -Po 'inet \\K[\\d.]+') With: HOST_IP=$(ipconfig getifaddr en0)

This seems to be the only Linux OS-specific bug in the workshop as Docker will work on any platform. Tbh, my solution is also kinda a OSX-specific hack. I think it would be better practice if HOST_IP was set as an environment variable.

[krisc]

@leovigna hmm yeah, we overlooked that WARNING. But I'm actually on Manjaro Linux ...

[leovigna]

So did you find a way to set HOST_IP? Are the docker instances able to connect?

Hi @leovigna, I have the same issue

Hey, I've struggled to set the whole thing locally as well, which it has not been as "plug & play" as in the video (but in fairness nothing never is).

My approach has been a bit bottom up after GORM wasn't able to connect to my local PostgreSQL instance (not containarised) on he first attempt using this repository.

A summary of what I've done is (for local development purposes):

1. Install Docker Engine, Docker Compose and be sure they work for not root users.
2. Install PostgreSQL 12 and configure both postgresql.conf and pg_hba.conf for being able to be reached from a container.
3. Set up the database user, database, etc.
4. Follow the Chainlink official documentation for just spinning up a node.
5. Go back to this repository and try to understand better the whole integration.

Now I'm blocked at the same point than you: prep-node.js fails at clUtils.getAcctAddr(), because this function is unable to send the GET request (http://localhost:6688/v2/user/balances). I've isolated the request in a minimal Truffle script and it does not work either. The funny thing is the request works both via browser and Postman.

Call using Truffle

Shell script call:

npx truffle exec scripts/smoke_test.js

        }
    ]
}

I will keep investigating what is going on. Any help appreciated @danforbes, otherwise I will ask at Discord.

Thanks

P.S.: the HOST_IP warn you get on npm start is because this command calls first npm stop, which calls docker-compose down, and the HOST_IP environment variable is not being passed.

[vnavascues]

Morning, quick follow up on the matter!

I was wrong and the function to blame is getSessionCookie(). I'm running Chainlink Node 0.8.12 (because it wasn't locked in the docker-compose.yml), and with this version the statement const cookie = res.headers["set-cookie"][0] assigns a wrong cookie. There are two items in the set-cookie Array and the one that matters starts with clsession=. As I can't assure their positions my quick fix is:

        res.on("end", () => {
          const clsessionIdx = res.headers["set-cookie"].findIndex((c) =>
            c.startsWith("clsession")
          );
          cookie = res.headers["set-cookie"][clsessionIdx];
          resolve(cookie);
        });

@Mvilsht hope it helps, but probably you have already sorted it out.

[danforbes]

Sorry for the very delayed reply, @vnavascues. I'm glad you were able to make progress on this. Since this repo clearly isn't being maintained I am going to archive it.
