RANGESLIDER BUG - Date filter dynamically bugging when value is different of None

Hey guys,

I’m building an application that will fetch some data based on an API… The application is basically:

The values of the range slider need to be dynamically generated… So I need to get min and max values based only on the checked options, but once I do add a value to my rangeslider it raises an error in my application;

It shows an error that doesn’t make any sense to me…

I do not have any component or variable called slider as it shows in the error. Below is my callback related to this problem:

Thank you in advance for any help to solve this problem
