http-functions put error

Hello. Please help my insanity. I need to have an http-functions put() method work to update my database and I’m running into the following error:

{error: {name:Error, errorGroup:User, code:WD_VALIDATION_ERROR}}

Here’s the kicker, if I comment out just the " wixData.update " line of code, it works! - meaning that my Postman call connects, although it doesn’t update. I can even change it to create a record using the wixData.insert method, and it works.

Could there be a problem with the wixData.update function internally on the Wix side?

My http-functions.js code was copied directly from WixCode. I’ve made sure my database permission is set to “Anyone”. I’ve tested it from the _functions-dev side, and get the same error. I even made a blank new database to test if it was something else on my original database. What am I missing?

I’ve included a screenshot of my .js code, and my Postman call.

thanks


Thanks
