Air Tab PATCH issues

I'm tearing my hair out trying to get a simple PATCH API call to change a value in my table. I'm using airtable.
I have a table, named AllTitles, which contains information regarding movies. I have a field in this table called 'liked' and the aim is to assign a value 1 to this cell when the user clicks a button. So I figured and nice simple PATCH would work. I set the default value to 0. The idea being that the title is marked as being liked, so I can filter liked titles and return these to the app. The KEY value for my table is called myid. I have added a column which calls the function RECORD ID() and this does indeed display the unique record id. The URL contains a variable at the end, you guessed it, the record id. When I copy and paste this URL into the browser bar it loads the correct record. However, I am getting a 404 error when I debug.

There are no query parameters set. I am at a loss as to what can be the problem when the generated URL works perfectly. It's not the most demanding JSON PATCH request in the world....
