deg2rad() expects parameter 1 to be float, string given

Description

I'm putting together a search on a site of ours which includes a location search. The user has the option to put in a postcode and distance, and the site searches events in that radius. I also have a bunch of other search parameters which can be set so I'm building an array to search by.

The code in question looks like this:

{% set queryParams = queryParams|merge({
	eventMap: {
		location: widgetEventPostcode ? widgetEventPostcode : 'KT22 7UD',
		country: 'UK',
		radius: widgetEventDistance ? widgetEventDistance : 1000,
		unit: 'mi'
	},
	orderBy: 'distance desc',
}) %}

When I put a postcode into the search form it's throwing the error deg2rad() expects parameter 1 to be float, string given which is on line 145 of MapService.php.

I understand it's a bit of an edge case and might be due to how I'm building my search query so if that's the case please let me know what I'm doing wrong.
