Root Cause Analysis

The Prisma Engine binary is compiled for a different architecture or operating system than the one used by AWS Lambda's Alpine-based runtime environment, resulting in a runtime incompatibility. This is due to the fact that AWS Lambda's Alpine environment has a different set of dependencies and libraries than the environment where the Prisma Engine binary was compiled, leading to a mismatch in the expected runtime environment.

● Configuration & Code Resolution

Add the following lines to your `package.json` file:
"scripts": {
  "build": "prisma generate && npm run build:lambda"
},
"install": "npm install --platform=linux --arch=x64 prisma"
And update your `lambda.function.js` file to include the following code:
const { PrismaClient } = require('@prisma/client');
const prisma = new PrismaClient();
Then, update your `Dockerfile` to include the following lines:
FROM public.ecr.aws/lambda/nodejs:14
RUN npm install --platform=linux --arch=x64
This will ensure that the Prisma Engine binary is compiled for the correct architecture and operating system, and that the necessary dependencies are installed.
