Problem ORS tool

[PeterClaro]

When I use the Isochrones from layer tool. I get an error, which should not be there following the instructions on the website. Does anyone know what could be done?

Here's what I did

Hey,
could you describe what you did, ideally providing a minimum viable input layer and the corresponding parameters that exhibit the bug?

It's rather hard to debug these issues without any information on what the input was.
