The params in ctx are unknown in custom controllers

Hello everyone, how are you?

I have a problem when creating custom controllers in strapi, I set up my project in JS, and when I want to configure custom endpoints I find that the parameters that I get in ctx are unknown.

Does anyone know what to do in this situation?

module.exports = createCoreController('api:example.Example', ({strapi}) =>({
    async customAction (ctx) {
        try {
            ctx.body.paramExample;
        } catch (error) {
            ctx.body = error;
        }
    }
}));

//This is the VSCode message 
//The property 'paramExample' does not exist in type 'unknown'.ts(2339)
//any
