Auto import fails to add due to VSCode typescript version

[rrivem]

• VSCode Version: 1.35.1
• OS Version: OS X 10.14.5

Steps to Reproduce:

1. Launch VS Code and open a javascript project and wait for the "Initializing JS/TS language features"
2. Open a js file and type a function/object exported from another module
3. Intellisense will show the symbol but when hovering, the "Auto import from '...'" does not
4. Clicking or hitting enter does NOT import the symbol.

Does this issue occur when all extensions are disabled?: Yes

I've found many issues reporting like #61660, but installing typescript@next globally does not fix the issue.

Tracking VSCode older versions, I tracked the issue started in version 1.28, works fine in 1.27 which uses typescript 3.0.3 internally, but installing [email protected] globally does not fix the issue either.

The only workaround I found was to go inside "Visual Studio Code.app" and installing typescript 3.0.3 locally in "Contents/Resources/app/extensions".

Here are the tsserver logs for TypeScript output:

A few potentially related TS issues:

• TypeScript Server Error - Cannot auto import get code fixes #31975
• Re-exporting a default export that doesn't exist with allowSyntheticDefaultExports true causes assert failures in getDefaultExportInfoWorker #29227

@rrivem Can you please confirm you see this using the latest typescript@next build. Also, can you share the project this happens on?

[rrivem]

Hi @mjbvz, I installed typescript@next within the VSCode application and doesn't fix the issue. Also setting the allowSyntheticDefaultImports=false in the jsconfig.json doesn't work either.

Sorry I can't share the project, but as @donovanhiland commented in #31975, it might be for the project having many files (~1,400).

We need a way to repro this failure

Closing as we cannot investigate this without repo steps
