Hi @Wian-TMC Thank you for opening an issue;

Did you provide an icon or used the default one?

[Wian-TMC]

My notification icon is set to an empty string

notificationIcon: '',

[mehdok]

Can you provide a valid icon and see if the error persists or not?

[Wian-TMC]

Sure.

I got the same issue. The error still persist even with a valid icon
