flowise local server setup error

I am trying to install local server for Flowise but running into the following issue:

C:\flowise\Flowise-main\Flowise-main>yarn install
yarn install v1.22.22
info No lockfile found.
[1/5] Validating package.json...
error flowise@3.0.11: The engine "node" is incompatible with this module. Expected version ">=18.15.0 <19.0.0 || ^20". Got "24.11.1"
warning flowise@3.0.11: The engine "pnpm" appears to be invalid.
error Found incompatible module.
info Visit https://yarnpkg.com/en/docs/cli/install for documentation about this command.

Please help!

Start with the yarn install output and the project's package.json, focusing on the declared Node.js engine range and the reported Node.js version. Check whether the installation instructions or setup entry point address this mismatch, then verify that the documented setup completes successfully with a supported version.
