cpqjavascript
I am working with the CPQ JavaScript Calculator. How do you see the debug logs? I mean it is running through as a Custom Script Record when running the CPQ UI. I looked through the pages with the Chrome debugging Tool but I am not seeing the Console.log outputs anywhere. I can see where it is calling the custom script but not the code.
export function onAfterCalculate(quote, lines, conn) {
console.log('onAfterCalculate 4');
return Promise.resolve();
}
Most probably the problem is in the order of execution of your code.
The onBeforeCalculate (and other event handler functions) return a Promise so that the calculating engine can wait for one, to finish processing, before starting another.
But in your code, you are starting a Promise (conn.query()) but exit from the event handler immediately with return Promise.resolve();
What you probably want is to return the promise in the event handler: return determineValidHistoricalPricing(...) so that the flow actually waits for your logic to finish.
Update:
CPQ requires its event handlers to return an actual Promise object (and not a promise-like JSForce connection), so for the above to work one must also wrap the JSForce query in a standard Promise, like so:
return new Promise(function(resolve, reject) {
conn.query(queryString)
.then(function (results) {
// ... processing results ...
resolve(results);
});
})
I've seen this happen when there is an issue in the Javascript. CPQ transpiles the code you paste into the script. I've found that first pasting my plugin code into https://babeljs.io/repl and checking for errors, helps ensure there are no issues.
There is a field on the Custom Script object called Transpiled Code. You can also check that it gets updated after saving your changes.
Edit: There is a Visualforce page you can add to your Custom Script page layout called Custom Script Save. It will tell you the Transpiling status.

I've found it easiest to add
debugger;statements where I want to check out what my code is doing. If you open developer tools before clicking "Calculate", your browser will put a break point on that line. This lets you inspect values, etc.
