In gh:mastra-ai/mastra#6852, the issue was: # Mastra 🤝🏻 Monorepos Hello everyone! 👋🏻 We love to see how many of you want to use Mastra. A lot of you are using Mastra as part of their monorepo setup, often authored in TypeScript. We hear you loud and clear (e.g. through issue like #1996) that there are currently pain points when trying to use TypeScript monorepos with Mastra. The gist of it is that Mastra currently doesn't support parsing TypeScript files by default. You either have to add a build step to your packages, compiling them to JavaScript or use the transpilePackages option.. The verified answer: In monorepos, if the build fails with the transpilePackages section set, try removing the transpilePackages section entirely. That resolved it for at least one setup; general monorepo support was still being worked on.. Issue URL: https://github.com/mastra-ai/mastra/issues/6852
