I'm migrating vue2 project to vue3 with below configuration

"vue": "^3.3.8",
"leaflet": "^1.7.1",
"@vue-leaflet/vue-leaflet": "^0.6.1"

Not getting any issue in the build. But graph is not loading on to the screen and getting below exception in console.

LMap.vue:411 Uncaught (in promise) TypeError: this.$slots.default is not a function
at Proxy.render (LMap.vue:411:32)
at Proxy.compatRender (vue.esm-bundler.js:5072:21)

Any help would be greatly appreciated.

Thank you.
