All my deployments started failing with this suddenly, any clue?

Now I am tackling this.

Deleted because I kept getting that error message so I thought restarting the server would help, but I do still see the same error

Hi @kumareth ! Could you share a deployment id and your project slug?

Hey, I was just having problems with Prisma. 1) My local environment kept saying "Bundling..." instead of restarting after changes. 2) 7 out of 10 times the dev command failed with RollupError. After removing all imports of PrismaClient, everything worked. Then after some googling I noticed my schema.prisma had provider = "prisma-client-js", but some examples using Hono had provider = "prisma-client". So what solve my problem was: - Changing from -js to just prisma-client and regenerating the client - Chaning the imports from generated/prisma (which meant /generated/prisma/index) to /generated/prisma/client 
generator client {
  provider = "prisma-client"
  output   = "../src/generated/prisma"
}
generator client {
  provider = "prisma-client"
  output   = "../src/generated/prisma"
}
And I don't know about the bundler.externals. At least in my local env (windows) it didn't make any difference

Thank you so much! I'll try this! I "resolved" this and some other errors I was seeing related to Prisma by using raw sql instead. Other build errors that I only saw on Mastra Cloud builds (sadly I don't have a log of it anymore to help you debug). Moved hosting to vercel instead for now. But, then I don't get a production playground, hopefully we get the playground on production builds soon 🙏 @Victor That works for Prisma!! Thanks~ can you share your bundler config in mastra? 
 bundler: {
    externals: [
      // Prisma packages (no longer used in workflows, but keep for safety)
      '@prisma/client',
      '.prisma/client',
      '@prisma/engines',
      '@prisma/client/runtime/*',
      '@prisma/client/runtime/library',
      '@/generated/prisma',
      '@/generated/prisma/*',
      '@/generated/prisma/client',
      // PostgreSQL client (used in CSV workflow)
      'pg',
      'pg-pool',
      'pg-native',

      'playwright-core',
      'playwright',
      '@browserbasehq/stagehand',
      // Peer dependencies of stagehand that need to be available at runtime
      'dotenv',

glad it helped you! but my bundler is just bundler: { externals: ["ioredis", "ai"] } I tried with pg, prisma, prisma/client, but it changed nothing, so I removed and keep as before. Also I don't use Mastra Cloud, I'm using AWS ECS/docker and github actions to deploy I think the bundler options are currently lacking details on the documentation. I don't get exactly what happens changing those options
