TypeError: Cannot read properties of undefined (reading 'isDynamic') is suppressing errors in getServerSideProps

Verify canary release

Provide environment information

I’m really at a loss for what causes this bug or how exactly to replicate it (which is one of the issues with the bug), but there’s a bit of discussion about it here: https://github.com/vercel/next.js/discussions/40373

The summary is that in certain cases NextJS will throw an error with the message TypeError: Cannot read properties of undefined (reading 'isDynamic'). I believe this happens when an error is throw in getServerSideProps, or possible anywhere in index.tsx, but I’m not sure. The problem is that the isDynamic error obscures the error that is actually being thrown, making debugging a matter of trial and error.

Describe the Bug

1. TypeError: Cannot read properties of undefined (reading ‘isDynamic’) is obscuring any errors thrown in getServerSideProps, and possible anywhere in index.tsx.

Expected Behavior

Any errors throw in getServerSideProps should report the actual error being throw, rather than the isDynamic error.

I honestly I have no idea how to reproduce this consistently.

OK, I actually think we can close this entirely. Our dd-trace plugin was severely out of date. Updating it to the latest addressed the issue.
