Hi, @Bhuwan,

There must be an error in your chaincode due to which your chaincode is getting crashed. A similar case has happened to me. Usually, your transaction will timeout if your chaincode crashed.

To debug, list all docker containers by:

docker ps

copy the id of your chaincode container and execute this command:

docker attach <container-id> -f

execute the invoke/query command again. If there is a crash, logs will be printed where you executed docker attach
