Hi

I use sequelize and postgress database, but when i build i have this error : 

⨯ ./node_modules/@sequelize/core/lib/sequelize.internals.js:30:1
Module not found: Can't resolve '@sequelize/mariadb'

https://nextjs.org/docs/messages/module-not-found

Import trace for requested module:
./node_modules/@sequelize/core/lib/sequelize-typescript.js
./node_modules/@sequelize/core/lib/sequelize.js
./node_modules/@sequelize/core/lib/index.js
./node_modules/@sequelize/core/lib/index.mjs
./server/models/Federation.ts
./src/app/api/route.ts

i also do this : 
const nextConfig = {
    webpack: (config, { isServer }) => {
      if (!isServer) {
        config.resolve.fallback = {
          mariadb: false,
          ['@sequelize/mariadb']:false
        };
      }
  
      return config;
    },
  };

still not works

i follow this :

and do this :
https://github.com/vercel/next.js/discussions/49432
      config.ignoreWarnings = [
        { module: /node_modules\/node-fetch\/lib\/index\.js/ },
        { file: /node_modules\/node-fetch\/lib\/index\.js/ },
      ];

Hi

i just find a source part of problem.

Maybe i use in the bad way 
  const sequelize = new Sequelize({ dialect: PostgresDialect });


Because when i do this , in a controller : 
export const POST = async (req: Request, res: NextApiResponse) => {
  const data = await req.json();

// if i comment, this it's work
  const sequelize = new Sequelize({ dialect: PostgresDialect });
  // await sequelize.authenticate();

  console.log("authenticate");

  // const federation = await Federation.create({ name })
  return NextResponse.json("federation")
}


Someone know what i did bad ?
