Issues importing a class in the provider folder of AdonisJS while creating TypeScript definitions.

Could anyone help me with an issue I'm facing while building a database wrapper for Prisma in adonis? I am trying to create a typescript definition for it, but I'm unable to import the Database class from providers/DatabaseProvider/database.ts. I've tried recreating the project multiple times, but the issue persists. Thank you smmmm contracts/DatabaseProvider/database.ts
declare module "@ioc:Evermore/Database" {
import Database from "providers/DatabseProvider/database";
const db: Database;
export default db;
}
declare module "@ioc:Evermore/Database" {
import Database from "providers/DatabseProvider/database";
const db: Database;
export default db;
}
providers/DatabaseProvider/index.ts
import type { ApplicationContract } from "@ioc:Adonis/Core/Application";

export default class DatabaseProvider {
constructor(protected app: ApplicationContract) {}

public register() {
// Register your own bindings

this.app.container.singleton("Evermore/Database", () => {
const databaseProv = require("./database").default;
return new databaseProv();
});
}

public async boot() {
// All bindings are ready, feel free to use them
}

public async ready() {
// App is ready
}

public async shutdown() {
// Cleanup, since app is going down
}
}
import type { ApplicationContract } from "@ioc:Adonis/Core/Application";

export default class DatabaseProvider {
constructor(protected app: ApplicationContract) {}

public register() {
// Register your own bindings

this.app.container.singleton("Evermore/Database", () => {
const databaseProv = require("./database").default;
return new databaseProv();
});
}

public async boot() {
// All bindings are ready, feel free to use them
}

public async ready() {
// App is ready
}

public async shutdown() {
// Cleanup, since app is going down
}
}
providers/DatabaseProvider/database.ts
import { PrismaClient } from "@prisma/client";

export default class Database {
protected DB: PrismaClient;
constructor() {
this.DB = new PrismaClient();
}
}
import { PrismaClient } from "@prisma/client";

export default class Database {
protected DB: PrismaClient;
constructor() {
this.DB = new PrismaClient();
}
}

"providers": [
"./providers/AppProvider",
"./providers/MongoProvider",
]
"providers": [
"./providers/AppProvider",
"./providers/MongoProvider",
]
like this

try moving out of the folder like /contracts/database.ts
// /contracts/mongoose.ts
declare module '@ioc:Mongoose' {
// Export everything from Mongoose
// Since that's what our provider is doing
export * from 'mongoose';
}

// providers/MongoProvider.ts
import type { ApplicationContract } from '@ioc:Adonis/Core/Application';
import Env from '@ioc:Adonis/Core/Env';
import mongoose from 'mongoose';

export default class MongoProvider {
constructor(protected app: ApplicationContract) {}

public register() {
mongoose.connect(Env.get('MONGO_URI'));

this.app.container.singleton('Mongoose', () => mongoose);
}

public async boot() {
// All bindings are ready, feel free to use them
}

public async ready() {
// App is ready
}

public async shutdown() {
await this.app.container.use('Mongoose').disconnect();
}
}

// any ts file
import { model, Schema } from '@ioc:Mongoose';
// /contracts/mongoose.ts
declare module '@ioc:Mongoose' {
// Export everything from Mongoose
// Since that's what our provider is doing
export * from 'mongoose';
}

// providers/MongoProvider.ts
import type { ApplicationContract } from '@ioc:Adonis/Core/Application';
import Env from '@ioc:Adonis/Core/Env';
import mongoose from 'mongoose';

export default class MongoProvider {
constructor(protected app: ApplicationContract) {}

public register() {
mongoose.connect(Env.get('MONGO_URI'));

this.app.container.singleton('Mongoose', () => mongoose);
}

public async boot() {
// All bindings are ready, feel free to use them
}

public async ready() {
// App is ready
}

public async shutdown() {
await this.app.container.use('Mongoose').disconnect();
}
}

// any ts file
import { model, Schema } from '@ioc:Mongoose';
im using mongoose, but should be the same for prisma

yup, still the same Hey, umm, I fixed it. I searched through the issues in the Adonis/core repo on GitHub, and it seems that there are some issues when using PNPM (which is what I've been using the whole time), so I switched to Yarn, and it's now working fine! Thank youuu.
