Hyperledger Composer - can't find transaction error - node.js

Question

I am making a blockchain application using hyperledger composer and have written my cto, with on transaction, and the script file with no visible errors. However, when i try submit a transaction it returns this error: Error: Could not find any transactions to execute for org.evidence.net.evidenceDeposit.
Here is my CTO file:
namespace org.evidence.net
enum type {
o storage
o device
o physical
}
enum status {
o collected
o stored
o withdrawn
}
asset EvidenceItem identified by evidenceItemId {
o String evidenceItemId
o String caseNo
o type Type
o status Status
o String optionalHash optional
--> person Holder
}
abstract participant person identified by id {
o String id
o String firstName
o String lastName
}
participant Investigator extends person {
}
participant EvidenceManager extends person {
}
participant FRT extends person {
}
transaction evidenceDeposit {
--> EvidenceItem EvidenceItem
--> EvidenceManager EvidenceManager
}
event FirstDeposit {
o String evidenceItemId
o String id
}
And here is my script file:

/**
* Transfer evidence from FRT to Evidence Manager
* #param (org.evidence.net.evidenceDeposit} tx - the evidenceDeposit transaction
* #transaction
*/
const NS = 'org.evidence.net';
async function evidenceDeposit(tx) {
// get asset registry for evidenceItem
const evidenceItemRegistry = await getAssetRegistry(NS + '.evidenceItem');
//Get participant registry for Evidence Manager
const EvidenceManagerRegistry = await getParticipantRegistry(NS + '.EvidenceManager');
const evidenceItem = await evidenceItemRegistry.get(tx.evidenceItem.getIdentifier());
//Make sure that the evidenceItem exists
if (!evidenceItem) {
throw new Error(' Evidence with id ${tx.evidenceItem.getIdentifier()} does not exist');
exit();
}
if (evidenceItem.status !== 'collected') {
throw new Error('Evidence with id ${tx.evidenceItem.getIdentifier()} is not in collected status');
}
// Get Evidence Manager ID
const EvidenceManagerID = tx.EvidenceManager.getIdentifier();
//Make sure Evidence Manager exists
const EvidenceManager = await EvidenceManagerRegistry.get(EvidenceManagerID);
if(!EvidenceManager) {
throw new Error('Evidence Manager with id ${EvidenceManagerID} does not exist');
}
//Update evidenceItem with new owner
tx.evidenceItem.holder = tx.EvidenceManager;
tx.evidenceItem.status = 'stored';
//Update the asset in the asset registry
await evidenceItemRegistry.update(tx.evidenceItem);
//Create deposit event
let FirstDepositEvent = getFactory().newEvent(NS, 'FirstDeposit');
FirstDepositEvent.evidenceItemId = tx.evidenceItem.evidenceItemId;
FirstDepositEvent.id = tx.EvidenceManager.id;
// Emit the Event
emit(FirstDepositEvent);
}
I have looked around and can't seem to find the problem. Any help is appreciated.

Please see the readme below as Hyperledger Composer has been deprecated for over a year.
