Prisma Client Error: Column User.stripe_customer_id Does Not Exist in PostgreSQL Database – A Comprehensive Guide to Resolution

Are you tired of getting the frustrating error “Column User.stripe_customer_id Does Not Exist” in your Prisma Client application? You’re not alone! Many developers have stumbled upon this issue, and it’s more common than you think. In this article, we’ll delve into the reasons behind this error and provide you with a step-by-step guide on how to resolve it once and for all.

What is Prisma Client?

Before we dive into the error, let’s take a quick look at what Prisma Client is. Prisma Client is a powerful ORM (Object-Relational Mapping) tool that allows you to interact with your database using a strongly-typed and auto-generated API. It’s a popular choice among developers due to its ease of use, performance, and scalability.

The Error: Column User.stripe_customer_id Does Not Exist

The error “Column User.stripe_customer_id Does Not Exist” occurs when Prisma Client attempts to query a column that doesn’t exist in your PostgreSQL database. This can happen due to various reasons, including:

• Mismatch between your Prisma schema and your PostgreSQL database schema.
• Incorrectly defined relationships between models.
• Outdated Prisma Client version.
• Corrupted or missing migration files.
• Manual changes made to the database schema without updating Prisma Client.

Step 1: Verify Your Prisma Schema

To resolve the error, start by verifying your Prisma schema. Open your `schema.prisma` file and check if the `stripe_customer_id` column is correctly defined:

model User {
  id       String   @id @default(cuid())
  name     String
  email    String   @unique
  stripe_customer_id String?
}

Make sure the column is defined with the correct data type and optional/required status.

Step 2: Check Your PostgreSQL Database Schema

Next, ensure that the `stripe_customer_id` column exists in your PostgreSQL database. You can do this by running the following SQL command:

\d+ users;

This will display the schema of the `users` table, including the columns and their data types. Verify that the `stripe_customer_id` column exists and has the correct data type.

Step 3: Update Your Prisma Client

Outdated Prisma Client versions can cause compatibility issues with your database schema. Make sure you’re running the latest version of Prisma Client by running the following command:

npm install @prisma/client@latest

or

yarn add @prisma/client@latest

Step 4: Run Prisma Migrations

Prisma migrations are used to apply changes to your database schema. Run the following command to apply any pending migrations:

npx prisma migrate dev

This command will create or update your database schema according to your Prisma schema.

Step 5: Verify Relationships Between Models

Incorrectly defined relationships between models can cause issues with your Prisma Client queries. Review your Prisma schema and ensure that relationships between models are correctly defined:

model User {
  id       String   @id @default(cuid())
  name     String
  email    String   @unique
  stripe_customer_id String?
  orders   Order[]
}

model Order {
  id       String   @id @default(cuid())
  user     User     @relation(fields: [id], references: [id])
  products Product[]
}

In this example, the `User` model has a relationship with the `Order` model, and the `Order` model has a relationship with the `Product` model.

Step 6: Clear Prisma Client Cache

Sometimes, clearing the Prisma Client cache can resolve issues with your queries. Run the following command to clear the cache:

npx prisma client reset

This command will clear the Prisma Client cache and reload your Prisma schema.

The “Column User.stripe_customer_id Does Not Exist” error in Prisma Client can be frustrating, but it’s often an easy fix. By following the steps outlined in this article, you should be able to resolve the issue and get your application up and running smoothly.
