Runtime error with latest version of Mastra core

I recently updated to a recent version of @mastra/core 0.23.3 and I get the following error at runtime, which never appeared before:

The error appears only when I am deploying my application on Koyeb while the local development environment (using a Devcontainer) works just fine. It seems to be related to some issues with slugify. Do you have any idea on how to solve this?

Hey @Mario Dagrada ! Could you try upgrading to @mastra/core 0.24.6 and let us know if you're still seeing this issue? We ship a lot of fixes weekly and 0.23.3 is already a month old 😉

Thanks. I updated to 0.24.6 and still get the same issue, unfortunately.

Could you try adding @sindresorhus/slugify to your externals, like this?

const mastra = new Mastra({
  externals: ["@sindresorhus/slugify"]
})

const mastra = new Mastra({
  externals: ["@sindresorhus/slugify"]
})
