I’m trying to update an existing stock item record using a PUT request:

 

but I’m getting the following "Object reference not set to an instance of an object." 500 error from the server. Why is this happening? I can retrieve the record just fine using a GET request.

You cant use filter with PUT.

You would need to pass inventoryID in body to update that stock item. See below:

Before
Postman update with inventoryID in body
Updated description using API

Are you able to GET that inventory using POSTMAN?

Also, maybe try changing description it in the UI just to confirm/compare behavior with API?

@RohitRattan88 yes, that’s the weird part. I can GET the inventory ID record just fine, and change the title via UI as well:

 

Very confused as to why the PUT is not working

This ended up being a problem with a customization which was causing issues with the InventoryMaintenance. Thanks for your help @RohitRattan88
