@fastify/swagger: Modify route.method in swaggerTransform function

💬 Modify route.method in swaggerTransform function

When using fastify.all for registering a route, openapi schema contains all possible methods for that route, that I want to limit to just POST. Directly modifying route.method in swaggerTransform function does exactly that, but I am wondering if that will break some things internally?

fastify.all(
	"/example",
	{
		config: {
			swaggerTransform: ({ schema, url, route }) => {
				route.method = ["POST"];
				return { schema, url };
			},
		},
	},
	(req, reply) => {
		///
	},
);
