ES6 got me! The same code in SuiteScript 2.0 passes all syntax checks, but when converted to SuiteScript 2.1 fails to upload to NetSuite. What the heck? I’m not even going to try to explain this. I’m just going to show the problem and the fix with examples.

This PASSES syntax checks but FAILS to upload to NetSuite:

This PASSES syntax checks and SUCCEEDS to upload to NetSuite:

The only difference is moving the reference to N/format inside the main function. Apparently this is something the NetSuite JavaScript compiler frowns upon, but the vsCode syntax checker is OK with.

My complaint is with the NetSuite error message. It’s ugly! I formatted it here to make easier to parse with the eyes. If you are reading this, you already know it comes out as a jumbled mess on the screen. Argh!

Here is the actual text you’d see on the screen, again I formatted it to make it readable. I’m including it in text to help find this article if you experience this error. It’s exactly what you see above.
