I am getting an error while I want to implement MarkerClusterer from @react-google-maps/api.
The error that I am getting is
No overload matches this call. Overload 1 of 2, '(props: MarkerClustererProps | Readonly): ClustererComponent', gave the following error. Type 'Element[]' is missing the following properties from type 'ReactElement<any, any>': type, props, key Overload 2 of 2, '(props: MarkerClustererProps, context: any): ClustererComponent', gave the following error. Type 'Element[]' is not assignable to type 'Element'.ts(2769) index.d.ts(378, 15): The expected type comes from the return type of this signature. index.d.ts(378, 15): The expected type comes from the return type of this signature.
You can check the codes below. (I am sharing only the relevant parts of my whole code)
