Fastify version

3.29.0

Plugin version

7.0.1 - 7.0.0

Node.js version

Description

On task startup I obtain this error:

fastify-plugin: @fastify/formbody - expected '4.x' fastify version, '3.29.0' is installed

I think that this check is wrong (this version must be compatible with Fastify 3.xx)

Steps to Reproduce

const Fastify = require("fastify");
const Formbody = require('@fastify/formbody');
const server = Fastify({
      connectionTimeout: 20 * 1000,
      logger: false
});
server.register(Formbody);
server.listen(3000,"0.0.0.0",(err,address)=>{
    if (err)
        throw err;
   else 
       console.log( "Server is active");
});

Expected Behavior

Plugin works as expected using Fastify v3.xx

Use v6.0.1, v7.x only supports Fastify v4 and above.

Ok It works.

Thank you for the support

I think the issue should remain open until README.md has been fixed. Right now it states the following:

This branch targets Fastify v3. Please refer to this branch and related versions for Fastify ^2.0.0 compatibility.

Nowhere does it tell which version should I use to target Fastify 3.
