You probably set beacon-blink-when-point-moves-horizontally or beacon-blink-when-point-moves-vertically to a boolean. They are integers :warning:

You can reproduce this error message by configuring:

  (beacon-blink-when-point-moves-horizontally t)
  (beacon-blink-when-point-moves-vertically t)

Instead of integers:

  (beacon-blink-when-point-moves-horizontally 10)
  (beacon-blink-when-point-moves-vertically 5)

It takes some tracing to figure out the issue.

You won't get any feedback unless you used setopt. Sadly, the use-package :custom keyword did not save me from having to debug this.

The variable name really seems like a boolean, but it is definitely an integer.

@junwei-wang I can submit a PR to generate a warning that will at least let people know. I think the issue is just that the names are not obviously integer types.

How would you like to proceed?
