Background Effects Error

I have made a custom slider that has a min of 0, a max of 1 and a step of 0.1

When I move the slider it gets the value and runs the code below:


video: {

processor: {

type: 'background-blur',

config: { strength: this.value },




Each time I change the value it just throws an error (see attached image)

this.value is a value between 0 and 1
