Error when using sourcemap for reporting an error: Can't resolve original location of error.
Summary
I am using rollup to create a library that has fluent-ui. I am getting this error.
devDependencies "@fluentui/react": "^8.65.1", "@fluentui/react-hooks": "^8.5.4", "@rollup/plugin-node-resolve": "^13.2.1", "rollup": "^2.70.2", "rollup-plugin-cleaner": "^1.0.0", "rollup-plugin-peer-deps-external": "^2.2.4", "rollup-plugin-terser": "^7.0.2", "rollup-plugin-ts": "^3.0.2", "rollup-plugin-visualizer": "^5.6.0",
Operating system: windows 10 Node.js: 16.15.1
I'm not seeing anything in your issue that explains why the rushstack repository is relevant. Looks like you should be filing this issue on rollup? https://github.com/rollup/rollup
https://www.npmjs.com/package/@microsoft/load-themed-styles
It's the repo listed for this library.
And I did ask the rollup plugin author https://github.com/wessberg/rollup-plugin-ts/issues/161
Ah, ok, that makes more sense. From a closer look at that message, the issue is with the default helper emitted by TypeScript being incompatible with the ESM transformation that Rollup is applying. The version of the __assign helper emitted when inlining the helpers doesn't do what is expected. Might work to release a new version of the library that compiles against ES2015+.
@dmichon-msft Hi David, I updated @fluentui but I am still getting the same error.
Is there something I missed?
@dmichon-msft @iclanton
I updated my packages to their latest versions and the errors are still there.
Which version of @microsoft/load-themed-styles are you using? The fix is in major version 2, since it was a breaking change to switch compilation target from ES5 to ES2017. You may need to use overrides (globalOverrides in common/config/rush/pnpm-config.json, or common/config/rush/.pnpmfile.cjs, or the equivalent in your repo's package manager) to have Fluent use major version 2 of @microsoft/load-themed-styles.
