Solution Style `tsconfig.json` is not working

Firstly, I am unsure if this is specific to coc-tsserver or whether it's an issue with typescript.

I am using solution style tsconfig.json (see https://devblogs.microsoft.com/typescript/announcing-typescript-3-9/#support-for-%E2%80%9Csolution-style%E2%80%9D-tsconfig.json-files). But it seems that the coc-tsserver is not picking the config file correctly.

When I run :CocCommand tsserver.goToProjectConfig, it errored with [coc.nvim] Config file not found.

But if I replace my tsconfig.json with one of the referred file, it works fine.

tsserver.goToProjectConfig asks tsserver's projectInfo for the config file that owns the current file. For a solution-style tsconfig.json ("files": [] + references), tsserver only reports a config when the opened file is actually part of one of the referenced projects — I verified with TypeScript 5.8.3 that a file inside packages/a/src returns packages/a/tsconfig.json. When the file is not covered by any referenced project, tsserver reports it as belonging to an inferred project (/dev/null/inferredProject*) and the command shows "Config file not found" — the same behavior as VSCode.

So if you get "Config file not found", check that the file you are editing is included by one of the referenced projects (its folder has its own tsconfig whose include covers the file). If it is and you still see the error with coc-tsserver 2.4.0, please share the project layout and :CocInfo. No coc-tsserver change is needed for this scenario.
