Hyperledger Fabric Custom chaincode invoke failed

Question

I'm trying to run a custom chaincode. I was able to deploy it successfully but when I run the invoke command using:

peer chaincode invoke -n mycc -c '{"Args":["write","hello_world", "200"]}'

Facing this error message:

Error: Error endorsing chaincode: rpc error: code = 2 desc = Error deploying chaincode: Failed to launch chaincode spec(Could not get deployment transaction from LCCC for mycc - Error deploying chaincode: Transaction or query returned with failure: transaction not found default/mycc)

Logs after successful deployment of chaincode on peer (Running peer in DEV mode):

Any pointer on where I am going wrong would be great. Thanks in advance.

Kindly include the command used to deploy the chaincode. I am wondering whether you did indeed name the chaincode as "mycc" with the -n switch — Ashishkel
This is the deploy command: peer chaincode deploy -n mycc -c '{"Args":["init","100"]}' — meraki

A couple of modifications to the invoke syntax might help.

If security is enabled, then a -u parameter should be used to specify a user who has already enrolled.
For the -n parameter, the chaincode ID could be tried rather than the chaincode name.

Example syntax for an invoke is included under the “Testing and verifying your local network” heading at https://hub.docker.com/r/ibmblockchain/fabric-peer/.
