can someone please help me on it, much appreciated & thanks in advance.

i'm using basic network folder and below script for network creation & install,instantiate and invoke chaincode.

Maybe you have forgotten the @Default decorator

@Contract(name = "MyContract",
        info = @Info(
                title = "My Contract",
                description = "",
                version = "0.0.1"
        )
)
@Default
public class MyContract implements ContractInterface {

Undefined contract method called

Is in the first few lines of the code.This means the function you passing to invoke is not present in the chaincode,Can you check the chaincode and see if the initLedger is present?or is there any spelling errors. Hope this was usefull.

In case you are facing this issue while instantiating a chain code, then you can override following method given in ContractInterface with your custom implementation.

/**
 * Invoked for any transaction that does not exist.
 *
 * This will throw an exception. If you wish to alter the exception thrown or 
 * if you wish to consider requests for transactions that don't exist as not an
 * error, subclass this method.
 *
 * @param ctx the context as created by {@link #createContext(ChaincodeStub)}.
 */
default void unknownTransaction(Context ctx) {
    throw new ChaincodeException("Undefined contract method called");
}

Otherwise, if the issue occurs while invoking existing transaction then ensure that annotation @Transaction() is present on transaction method.
