i am trying access parts of the url from a fastify server.

the url looks like this for example:

http://localhost:3001/query_tile/10/544/336

in the fastify server i need the values for z/x/y. i am trying to do something like this:

interface BodyType {
    z : string
    x : string
    y : string

  }
  

fastify.get('/query_tile/:z/:x/:y', async (request : FastifyRequest<{ Body: BodyType }>, reply) => {

    const { z, x, y } = request.body;
    console.log(z,x,y, request.body)
// ....
}

but in return i get this error message:

{"statusCode":500,"error":"Internal Server Error","message":"Cannot destructure property 'z' of 'request.body' as it is undefined."}

what would be the right way to access these values?

Thanks a lot!!
