Question Required parameter currencyId was null or undefined when calling incrementPlayerCurrencyBalance.

Hi I'm having a problem with using the economyAPI through cloud code. I can get the currency balances to increment and decrement when using the cloudcode parameters to set the currencyID as per the examples, but when I try and hardcode the currencyID I get the error:

Required parameter currencyId was null or undefined when calling incrementPlayerCurrencyBalance.

Here's my code:

Code (JavaScript):

1.  
2.     const lunchBoxCurrencyId = 'LUNCHBOX';
3.     const currencyId  = params.currencyId;
4.  
5.     // log typeof and value
6.     logger.info(typeof currencyId);
7.     logger.info(typeof lunchBoxCurrencyId);
8.     logger.info( currencyId + " == " + lunchBoxCurrencyId);
9.  
10.     // works:
11.     const increment = await currencies.incrementPlayerCurrencyBalance({ projectId, playerId, currencyId, currencyModifyBalanceRequest: { amount: 10 } });
12.  
13.     // doesnt work:
14.     const increment2 = await currencies.incrementPlayerCurrencyBalance({ projectId, playerId, lunchBoxCurrencyId, currencyModifyBalanceRequest: { amount: 10 } });
15.  
16.  

And this is what is output in the console:

info string

info string

info LUNCHBOX == LUNCHBOX

Im sure its just some basic misunderstanding of javascript on my behalf but I dont understand how 2 variables with the same type, scope and value can have different results.

 

Ah Ive fixed it myself the variable passed into the method has to be named

currencyId  

!
Still getting used to Javascript

 

I met the same issue... By the way, what does this JS Grammar called ?
