Unable to edit chaincode

[xinhan1989]

Sorry I'm unsure if this is the correct place to ask this question. I've been having trouble changing the chaincode and re using it with the cp-web app on Bluemix. The error I constantly get is:

2016-04-12T09:11:38.312+1000[App/0]OUT[ibc-js] Deploying Chaincode - Starting
2016-04-12T09:11:39.356+1000[App/0]OUT! looks like a deploy error, holding off on the starting the socket
2016-04-12T09:11:39.356+1000[App/0]OUT[ibc-js] deploy - failure: 400
2016-04-12T09:11:39.357+1000[App/0]OUT details: { Error: 'Error getting chaincode package bytes: Error generating hashcode: Error getting code process done with error = exit status 1' } }

These are the steps I follow:
Download code
Make Change at line 288: owner.Quantity = cp.Qty to owner.Quantity = 100.0
upload code to a github and then replace the zip file within app.js to my new git

Any idea of what could trigger the error? If this is the wrong place I'll move the question to the cp-web application instead.

Cheers,
William

I assume your talking about the code located here. The chaincode looks good! I suspect one of the parameters for configuring the chaincode in app.js is wrong. Could you please verify that your chaincode configuration looks like this:

chaincode: {
zip_url: 'https://github.com/xinhan1989/ziptest/archive/test.zip',
unzip_dir: 'ziptest-test',
git_url: 'https://github.com/xinhan1989/ziptest'
}

Yup, that's the code I'm talking about. the app.js does indeed look exactly like that, would there be anything else I'd need to add to it? From the logs I can see that the chaincode gets downloaded, unzipped and can read the files (I can see logs like [ibc-js] Found cc invoke function: createAccounts). but when it gets to the deploy function in the ibc it seems to simply suddenly produce the error I mentioned at the top. Currently reading through the IBM blockchain code to see if I can pinpoint where the error is generated but having trouble.

thanks for the help by the way!

Cheers,
William

Hi Gari,

I've tried using integers as well, but still the same problem. I doubt it is the chain code itself as simply using the exact chain code but from a different github gives me this error.

Cheers,

@xinhan1989 - the error is most likely caused by the fact your chaincode does not exactly compile. I believe that owner.Quantity is actually typed as an integer not a float. Go does not do implicit type conversions. Can you try changing owner.Quantity = 100.0 to owner.Quantity = 100
