Unable to resolve module `promise/setimmediate/*`

[kevinlinv]

Context

Note: this is a continuation of #2147 that may have been closed based on a workaround, not an actual resolution.

Quoting this comment: #2147 (comment)

The issue seems to be that because only the react-native module lists this as a dependency, it is stored in the node_modules/react-native/node_modules/promise path. This will not be searched by Metro for this require.

Adding promise to the projects depenencies has the effect of moving the promise module to node_modules/promise, which is one of the paths that is searched.

The correct fix is for promise to be defined as a dependency of @sentry/react-native which should then correctly place the promise module in node_modules root.

Personally I would reopen this and fix the underlying issue as you shouldn't be requiring any modules that are not defined in your dependencies explicitly.

And this continues to happen to others, latest reported in May #2147 (comment), and this issue now.

Steps to Reproduce

• Setup Webpack + Re.Pack plugin for bundling
• Install the react-native SDK
• Import it, and receive an error about being unable to resolve module promises

Expected Result

No module promise resolution errror at bundle time.

Thank you for reporting. We will investigate this and iterate back 🙇

[antonis]

Thanks for the detailed write-up and for connecting the dots back to #2147 — the diagnosis is correct. @sentry/react-native does require('promise/setimmediate/*') without declaring promise as its own dependency, relying on React Native's transitive copy (react-native → promise@^8.3.0). That resolves fine with a flat/hoisted node_modules, but breaks under strict/isolated layouts like pnpm (your .pnpm/ paths) and under Re.Pack/webpack resolution, which won't reach into react-native/node_modules/promise.

Adding promise to your app's own dependencies, matching the version RN ships (currently ^8.3.0), places it where your bundler searches:

npm install promise@^8.3.0    # or: yarn add / pnpm add

For pnpm specifically, you can instead hoist it via .npmrc:

public-hoist-pattern[]=*promise*

Let us know if that helps 🙇
