time slider using the results of supervised and unsupervised classification as the data

[Kakar3737]

I am currently trying to add a time slider on the map to display the result of unsupervised classification of an area. I already made an image collection from the result of the classification by adding the result.randomVisualizer() into an Earth Engine list and using the code bellow to convert it into an image collection

and this is the code i use for the time slider

But I got this error

What does max and min here means exactly and how do I fixed it if possible? Thank you

Hard to debug without a complete script that can reproduce the issue
