Description

Hi, I have an Angular 6 project in which we are using "@sentry/browser": "^5.0.6". This project uses GitLab CI tools to build a docker image for running our tests and deploy it. Today, we tried to launch the jobs and the typescript build failed with the following error code:

ERROR in node_modules/@sentry/utils/dist/misc.d.ts(89,48): error TS2304: Cannot find name 'unknown'.

The weirdest thing is that last time we run the jobs (October 2nd) everything was fine and we haven't change any single line of our project & configuration since then.

Do you have any clue? I'm pretty sure that it is something really stupid...

Our package.json is:

Thanks a lot, if you need further information, just ask.

Edit: Of course, I tried to update the sentry version to the latest one (5.9.1 and got the same results

unknown is a type that was introduced in Typescript 3 and you are using Typescript 2. However, we had unknown references in the codebase since v4 of the SDK, so I'm not sure how it could work for you before? 🤔

Hi kamilogorek, as you said we use TypeScript 2.9. I have been playing with npm and the sentry/browser versions today and it seems that the last version it works for me is @sentry/browser: 5.6.3. I have checked the release history in npm (https://www.npmjs.com/package/@sentry/browser) and I see that @sentry/browser: 5.7.0 was released a week after my last successful deploy, so everything makes sense to me.

For now I'll keep my package in the 5.6.3 version.

Thanks for your help

@franciscovelez you can easily workaround it by declaring unknown type yourself like so:

declare global {
  type unknown = any
}

ooor to be more exact if you want:

export type mixed = { [key: string]: any } | object | number | string | boolean | symbol | undefined | null | void

declare global {
  type unknown = mixed
}
