In the chaincode (in Golang) I have the following function:

func (s *SmartContract) f(ctx contractapi.TransactionContextInterface, arr []string) error { /* function details */ }

When I attempt to call this function via the Node.js SDK,

contract.submitTransaction('f', my_array);

where my_array equals ["v1", "v2"]. I get the following error

message=Error managing parameter param0. Conversion error. Value v1,v2 was not passed in expected format []string

What should be the right way to invoke the chaincode function via the SDK?
