What did you do?

<script setup lang="ts">
import type {  BmButtonSlots } from "./button.type";
// ...
const slots = defineSlots<BmButtonSlots>();
</script>

<template>
    <BmButton>
        <slot v-else name="icon">
            <BmIcon v-if="icon" :icon="icon" />
        </slot>
        <span class="label-wrapper" :class="{ 'sr-only': isIconVariant }">
            <slot>
                {{ label }}
            </slot>
        </span>
    </BmButton>
</template>

I 'll try to reproduce on a stackblitz.
That could lead me towards what I am doing wrong here. Since it works on your side , it might well be an issue on my project config

here's a Stackblitz with that issue :
https://stackblitz.com/edit/vitejs-vite-wxnegeku?file=src%2Fcomponents%2FHelloWorld.vue

in COmponent HelloWOrl you have a slot with a DefineSlot() where MySlot is an interface imported from a file located at src/

When running npx eslint ./src, we have a warning on defineSlot

You'll need to configure the following parameters:

"parserOptions": {
  // ...
  "project": ["./tsconfig.app.json", "./tsconfig.node.json"],
  "extraFileExtensions": [".vue"]
}
