How to pass and handle parameters Durable functions v4 javascript?

I’m very new with durable functions V4 in javascript but I cannot get this activity to run properly. I always get an error as apparently I’m not passing in the Instance ID correctly.

What am I doing wrong here? The tutorial page on the microsoft website was of no use.

Here is the code:

df.app.orchestration('reportOrchestrator', function* (context) {
   try {
       const instanceId = context.df.instanceId; // Get the current orchestration's instance ID
       context.log(`Orchestration instance ID: ${instanceId}`);

       const lsFile = { instanceID: instanceId }; // Pass instanceID in an object
       const token = yield context.df.callActivity('TokenManager', { instanceID: instanceId }); 

context.log(`Token retrieved: ${token}`);


return token;

  // const result = yield context.df.callActivity('PipelineQuery', { token });

  } catch (error) {
    return error.message;
    context.log(`Error in orchestration: ${error.message}`);
    throw error;
  }
});
df.app.activity('TokenManager', {
   handler: async (context) => {
        const log = context.log;

         const lsFile = context.getClient().instanceID; // Direct input passed from the orchestrator

if (!lsFile || !lsFile.instanceID) {
    //log("InstanceID is missing or undefined");
    throw new Error("InstanceID is missing or undefined,", context);
}

const instanceID = lsFile;
//log(`Orchestrator Instance ID is ${instanceID}`);

let functionID = "POST Reports Orchestrator";

try {
    // Make the POST request to retrieve the token
    const tokenResponse = await axios.post(logicAppURL, {
        requestType: "GET_TOKEN",
        functionID: functionID,
    });

    // Check if token was successfully retrieved
    if (tokenResponse.data && tokenResponse.data.token) {
        //log("Token successfully retrieved");
        return tokenResponse.data.token;
    } else {
        //log("Token could not be retrieved. Functions will generate their own token");
        await mandrillGeneralError(log, "Error retrieving token on POST Reports Orchestrator Token Manager function app in Azure.");
        return ""; // Return empty token if retrieval fails
    }

} catch (error) {
    //log(`Error retrieving token: ${error.message}`);
    await mandrillGeneralError(log, `Error retrieving token: ${error.message}`);
    throw error; // Throw the error so it's logged properly by Durable Functions
}
}
  });
