Not able to instantiate "mychannel"

fimas123

With hopes that i am right here i need some support for solving a problem regarding the hyperledger course.
Currently i am not able to instantiate the mychannel in the Lab 4.1

**When i enter following command as mentioned in the documentary:
**peer chaincode instantiate -n simple_cc -v 1.0 -C mychannel -c'
{"Args":[]}
' -o orderer.example.com:7050

**i get the following response:
**Error: could not assemble transaction, err proposal response was not successful, error code 500, msg error starting container: error starting container: Failed to generate platform-specific docker build: Error returned from build: 2 "# github.com/simple_chaincode
chaincode/input/src/github.com/simple_chaincode/simple_chaincode.go:48:91: syntax error: unexpected newline, expecting comma or )
chaincode/input/src/github.com/simple_chaincode/simple_chaincode.go:57:46: syntax error: unexpected ) at end of statement
"
So i am stucked and not able to follow the next steps for solving this course.
If this is not the right place for asking, maybe you can redirect my question?
Best regards

@fimas123,
Hello let's try to work through this issue. As you know the labs rely on the correct completion of all the prior steps. When you executed the prior two commands you confirmed your chaincode was properly installed and your peer is a member of MYCHANNEL ?

Hello,

yes that's correct. My Peer is a member of Mychannel and the chain code was properly installed. The response is as mentioned in the document
