Happens even when we pin import-in-the-middle to 1.8.0

[timfish]

This appears to be because the tsx and import-in-the-middle loaders are registered in the wrong order. import-in-the-middle is being passed TypeScript which it was never designed to parse.

privatenumber/tsx#571

[timfish]

This should hopefully have been fixed by the numerous PRs recently merged at import-in-the-middle.

Specifically for tsx, import-in-the-middle now gracefully handles source code it can't parse by falling back to the parent loader. This does mean that iitm won't be able to hook TypeScript files but that's likely not much of a concern for now.

While we wait for this to be released, there is a patch available that combines all the fixes. If anyone can confirm this patch fixes this issue that would be super helpful!

[AbhiPrasad]

With the newest release of import-in-the-middle v1.9.0 this should be fixed.

If you upgrade to a fresh install of the latest version of the Node SDK it should use [email protected] by default.
