Open Declaration results in "TypeScript Server Error (5.2.2) - Debug Failure. False expression"

[sebthom]

It seems that after upgrading to Eclipse 2024-03 open declaration via F3 is not working anymore at all. The error message isn't really helpful.

java.util.concurrent.ExecutionException: org.eclipse.lsp4j.jsonrpc.ResponseErrorException: <semantic> TypeScript Server Error (5.2.2)
Debug Failure. False expression.
Error: Debug Failure. False expression.

There have been some updates to language servers recently. Can you please retry with latest build?

For me, this happens randomly during coding. I must restart my IDE to fix this issue.
Not every restart solves this problem. Then I must restart multiple times.

Any update for this issue?

[mickaelistria]

Thanks for verifying.
I don't have further hint to provide here and personally cannot spend time on this issue for the next months or so because of higher priority tasks in my todo-list.
I think you could start by looking at the code of the tsserver to identify what is the "False expression" and then evaluate if the issue is purely on tsserver (thus it should be reported there), or whether it is an issue of integration missing some steps or configuration.
If you're comfortable with Eclipse plugin development, you can also tweak the JSTSLanguageServer class to add the --node-inspect flag to the launch so that the LS starts in debug mode and you can then connect a debugger (from another IDE instance!) to it and hopefully identify the cause of the error.

[mplukas]

Very superficial analysis.

The problem started after WWD switched to the TypeScript sever version 5.2+ (WWD release 1.3.1+).
It is caused by TypeScript 5.2 PR microsoft/TypeScript#54504, more specifically this change in the PR: "ensures that project always correctly represents the program state same as that of LS so that its reflected correctly for all purposes." It adds the assert that fails when TypeScript server is used from WWD:

    const oldProgram = this.languageService.getCurrentProgram();
    Debug.assert(oldProgram === this.program);

Have no idea if WWD or TypeScript server misbehaves here.

Some workaround:
If the project uses older than 5.2 TypeScrip version, then one can switch Eclipse WWD preference "JS/TS (Wild Web Developer)/TypeScript version used ..." to "Project" instead of "Eclipse". Then older TypeScript server from the project can be successfully used.

[jcompagner]

i do wonder if this is not more a LSP problem then a WWD problem?

[jcompagner]

this is a bit weird, i have setup my environment again to just debug WWD
But in a simple angular test project i couldn't get the above to be reproduced.
So then i just imported my main big angular project and until now also no problem.. So i still a bit confused when and why this happens.
