Description

An unexpected behaviour occurs when registering the plugin, causing a plugin timeout with a log error.

Plugin did not start in time: '@fastify/redis'. You may have forgotten to call 'done' function or to resolve a Promise"}

for example: registering the plugin as in
fastify.register(fastifyRedis)

or by wrapping it in a plugin, as in:

export default fastifyPlugin(async function redisPlugin(instance) { instance.register(fastifyRedis, { host: "0.0.0.0", }); });

or

export default fastifyPlugin(function redisPlugin(instance, options, next) { instance.register(fastifyRedis, { host: "0.0.0.0", }); next(); });
Both cause the log error and prevent some features from working accurately, like redis.set();

I've figured it out. The problem was that I had not set up a Redis server, so I did that with Docker, and everything went fine.
