💻 Code

My only repro is half-way through the build of a large repo, so I don't think I can isolate it to a code snippet.

Agoric/agoric-sdk#9476 changed the typescript from,

- typescript@^5.5.0-beta
-   version "5.5.0-dev.20240426"
-  resolved "https://registry.yarnpkg.com/typescript/-/typescript-5.5.0-dev.20240426.tgz#e9ba7d0b3cdaa54021faca61d1bc399e4766c93b"

+ typescript@^5.5.1-rc:
+   version "5.5.1-rc"
+   resolved "https://registry.yarnpkg.com/typescript/-/typescript-5.5.1-rc.tgz#4be420f1ecb5e66c52a7cb11444f06f02294c977"

A CI job builds each package topologically.

🙁 Actual behavior

The job started failing with:

Error: Debug Failure. False expression.

In the debugger I see that it happens while looking for escapedName: 'globalThis' in the context of this file.

🙂 Expected behavior

Continues to build like the beta and past releases.

Additional information about the issue

Our repo makes use of a hack to make types available both ambiently and by explicit imports.
https://github.com/Agoric/agoric-sdk/blob/e7b0cebd17f093793e93f4f236921cb4a3f595b8/packages/internal/exported.d.ts#L17-L29

The motivation for this is in transitioning from ambient types to define exportable types and retain backwards compatibility with consumers expecting ambients.

@turadg are you able to reproduce this locally? I’m hitting something else first when I try. Here’s what I’ve got:

gh pr checkout 9476
yarn
yarn lerna run --reject-cycles --concurrency 1 prepack

...

lerna ERR! npm run prepack exited 1 in '@agoric/zoe'
lerna ERR! npm run prepack stdout:

> @agoric/[email protected] prepack
> tsc --build tsconfig.build.json

tools/fakeVatAdmin.js(13,23): error TS2307: Cannot find module '../bundles/bundle-contractFacet.js' or its corresponding type declarations.
lerna ERR! npm run prepack stderr:
npm ERR! Lifecycle script `prepack` failed with error:

@andrewbranch a yarn build makes the bundles.

I just slimmed Agoric/agoric-sdk#9476 to one commit adopting TS 5.5 rc1 then rebased on master. Here's my local repro,

git checkout ta/typescript-5.5
git clean -dfx
yarn install
yarn build
yarn lerna run --reject-cycles --concurrency 1 prepack

ends with,

> @agoric/[email protected] prepack
> tsc --build tsconfig.build.json

lerna ERR! npm run prepack stderr:
/opt/agoric/agoric-sdk/node_modules/typescript/lib/tsc.js:120157
      throw e;
      ^
