Hello Mattew,

 

Thanks for your answer.

As i am a beginner with nodejs, I’m not sure to understand your comments.

And by searching  in Node.js documentation, I don’t find the solution to my problem.

So I send you 2 files attached to this mail:

  1. assetTransfer.js which is the file coming with your package: I have just added inside CreateAsset function:
  1. console.info(`INFO YAM CreateAsset`); // to try to create a trace on my linux terminal
  2. fs.appendFileSync(`YAM.txt`, `SALUT`) //  to try to create a trace in a new file named YAM.txt
  1. trace-23_03_2022.txt : this is the trace of all my commands I launch to do my test (see lines 771 and 785)

 

My 2 problems are:

  1. I get no log trace `INFO YAM CreateAsset` with console.info on my linux terminal
  2. No trace file  YAM.txt  is created with  fs.appendFileSync  

 

So my question is:

Do I have to add something in my code to make work these 2 kinds of traces (on my terminal and in a trace file)?

 

I hope these elements will help you to solve my 2 problems.

If you need others information’s, please tell me which or what commands you want me to launch in my terminal.

 

Thanks you in advance.

 

Best regards.

 

Yannick.

Hello, just to confirm have you looked in the container that is running the chaincode.   It's a separate docker container.

 

The Winston logger that the chaincode libraries use is also available via the context argument on transaction functions.

 

Check the Node.js API docs for info

Hello,

 

I use /fabric-samples/asset-transfer-basic/chaincode-javascript/lib/assetTransfer.js coming from your package

 

But my problem is :

The javascript instruction console.info or console.log doesn’t produce any trace on my linux terminal.

How can I solve this problem please ?

If possible, i'd like also put my code traces in a text file with this instruction console.log, but how do that ?

 

Thanks in advance.
