Element registry not working on modeler

[Gravity_town]

Hi, Here is my code for colouring an element in BpmnModeler.
The elementRegistry works fine, but elementRegistry.get does not…

The code

    const elementRegistry = modeler.get("elementRegistry");
    console.log('elementRegistry',elementRegistry)

    const startEvent = elementRegistry.get('Activity_1iadx4f');
    console.log("startEvent", startEvent )

the element registry by chrome inspect

The error

As you can see, the start event is undefined even when Id is correct.

why is this error occuring?

Sorry if the format or details of question are not upto the mark, if needed any extra details i will update.
Thank you

In which place do you try to get the element? Before or after the diagram import?

Chrome dev tools show that the elementRegistry changed after your console.log (via the i icon). A possible indication that you try to access the element before it was added.

Yes solved.
I Used the async and await method to solve it.
