I'm recieving a weird 400 status when I try and filter a get items request dynamically. I'm trying to return Items that were created yesterday to email them to the appropriate parties, but I keep recieving a 400 status when I add the utcNow() function into the Filter query line of the get items. Here's the wierd part, if I write in the date (ie: '2019-01-01') the filter works fine,but when I use the utc it fails. I've tried several version, one defining a string variable, one using the compose(as seen below) and one putting the utcNow() function directly into the filter query line.Any help would be greatly appreciatted.
Here is the flow:

Here is the Error:
