Debug Failure. False expression in TS 2.9 #24577

egoroof · 2018-06-01T17:29:16Z

TypeScript Version: 2.9.1

Search Terms: Module build failed: Error: Debug Failure. False expression. lastLocation.kind 273

Code

// hard to do a *self-contained* demonstration of the problem :(

Expected behavior:
Should compile without fail :)

Actual behavior:
Just updated typescript from 2.8.4 to 2.9.1 and got this error:

ERROR in ./node_modules/2gl/src/Buffer.js
Module build failed: Error: Debug Failure. False expression.

We use webpack@4 with ts-loader@4 and got this error. It happens with node8 and node10 on windows, macos and linux. It compiles without error in typescript 2.8, 2.7 etc.

I went to resolveNameHelper (\node_modules\typescript\lib\typescript.js:27843) and find the assert line:

 ts.Debug.assert(lastLocation.kind === 273 /* SourceFile */);

I've added a condition before it:

if (lastLocation.kind !== 273) {
    console.log(lastLocation.kind);
}

And got 296. I don't know what it means but tell me how I can help further.

The text was updated successfully, but these errors were encountered:

ghost · 2018-06-01T17:44:30Z

That kind is JSDocTypedefTag, so the error probably involves a @typedef somewhere in your code.

egoroof · 2018-06-01T18:06:36Z

Yeah, removing @typedef from ./node_modules/2gl/src/Buffer.js fix the problem - Compiled successfully

Snesi · 2018-06-06T20:02:09Z

I'm getting the same error, but I have no idea how to fix it. I do not have any @typedef in the code.

I also just started getting this error after updating from 2.8.4 to 2.9.1, and I am using webpack 4 with tsloader.

This is the error I'm getting:

ERROR in ./src/index.ts

Fix should be in typescript@next today, can you give this a quick try and confirm that it is indeed fixed?

Snesi · 2018-06-07T12:52:26Z

Yeah! That worked 😃

mattheworiordan · 2018-06-14T18:19:49Z

We have this same issue reported to us and I can reproduce locally with Typescript 2.9.2, 2.9.1 and even 3.0.0-dev*. But on 2.8.4 everything works fine.

Sadly no reference is given to the location of the False expression, and no @typedef is used in ably-commonjs.js.

@mhegazy do you have any suggestions on how we can try and identify what part of the file is causing this issue so that we can fix / raise a suitable issue?

ghost · 2018-06-14T18:50:59Z

@mattheworiordan That has nothing in common with this issue besides being an assertion failure, so I made a new issue for it: #24963

mattheworiordan · 2018-06-14T19:03:01Z

Thanks!

I have this problem using:

info "typescript@3.1.6" has binaries:
   - tsc
   - tsserver
✨  Done in 4.58s.

It happens on a file where I use both require.requireActual() and import (cause it's a Jest mock file)
