Fails to reexport property at build time

[garthenweb]

🐛 bug report

Using @sentry/browser fails at build time with Error: node_modules/@sentry/utils/esm/index.js does not export 'timestampWithMs'.

🎛 Configuration (.babelrc, package.json, cli command)

See https://github.com/garthenweb/parcel-bug-report-examples/tree/bug/sentry-does-not-export-timestampWithMs

🤔 Expected Behavior

Should create a proper build that is executable in the browser.

😯 Current Behavior

Fails with Error: node_modules/@sentry/utils/esm/index.js does not export 'timestampWithMs'. See https://github.com/garthenweb/parcel-bug-report-examples/tree/bug/sentry-does-not-export-timestampWithMs for more.

💁 Possible Solution

timestampWithMs is exported correctly in node_modules\@sentry\utils\esm\misc.js which is reexported in node_modules/@sentry/utils/esm/index.js.

timestampWithMs uses another export called crossPlatformPerformance, maybe this is the source of the issue?

Maybe related to #4216 but the error is different.

Works without scope hoisting.

I've identified the problem, will be fixed after the refactoring in #4411 landed.

(Note to my future self: tests and an ugly fix can be found in https://github.com/parcel-bundler/parcel/tree/resolveSymbol-wrapped-reexport)

@mischnic Are these fixes ever going to make it into 1.x? If not, could one avoid tree shaking this particular module only?

[mischnic]

No, also because Parcel 2's scope hoisting implementation has diverged (improved) too much at this point.

If not, could one avoid tree shaking this particular module only?

That isn't possible.

@xtrinch fwiw (in the sort term) pinning@sentry/browser to version "5.9.1" resolved this issue for me in 1.x

Thanks @drewsynan, wish there was a better fix, but that works for me!
