Excessive stack depth comparing types with TS 3.2

Code

import { PartialDeep, pick } from 'lodash';

type MapFunc<T> = (data: PartialDeep<T>) => PartialDeep<T>;

function testFunc<T>(): MapFunc<T> {
  return data => pick<PartialDeep<T>>(data, []) as PartialDeep<T>;
}

{
  "compilerOptions": {
    "target": "es2018",
    "module": "commonjs",
    "lib": ["es2018", "dom"],
    "strict": true,
    "noEmitOnError": true
  }
}

Expected behavior:
This code should compile with TS 3.2 as it will with TS 3.1

Actual behavior:
Compliation fails with the following error

error TS2321: Excessive stack depth comparing types 'PartialDeep<T>' and 'PartialDeep<PartialDeep<T>>'.


Found 2 errors.

I can confirm, that this issue still persists in [email protected]..
This thread, however, is a duplicate of #21592 .

This issue was introduced somehwere in 2.7.x - and has been moved from milestone to milestone to get fixed. Unfortunately, this has not been the case for now :(

[gabrielbiga]

Same issue here with TypeORM. :(

error TS2321: Excessive stack depth comparing types 'any' and 'FindConditions'.

[johannesschobel]

I think, the TypeORM related issue is the most common threat, why people end up in this issue here, haha ;)

[vitia]

This issue is a deal breaker :-(

[pleerock]

Can you guys please check it in the 0.2.15-rc.1 ? (npm i [email protected])

[anodynos]

EDIT: it works with npm i [email protected]

Unfortunately @pleerock I get the same with 0.2.15-rc.1 (TS 3.3.3333, ts-node: 8.0.3):

Weirdly enough it works fine with just a $ tsc compilation.

[pleerock]

The only way I could reproduce this issue is when I did gulp package (that does typescript compilation inside using gulp-typescript), using tsc is also fine to me. Then I changed some of the code (still valid typescript code, I just restructured something) and gulp compilation worked fine. I thought issue is fixed. @anodynos can you please provide some small reproduction where me (and maybe typescript team) can test this issue?

[anodynos]

FYI update: I hope I get this tested during Easter with latest TypeScript & ts-node and create a small reproduction repo :-)

[lucianosantana]

I confirm it works with [email protected]. I'm using that as a temporary workaround, since we were on [email protected] before. I've also tested with the latest version 3.4.3 and it's still broken.

For all the tests I was using [email protected]

Just got hit by this in TS 3.6.2 which Renovate bot just attempted to update to and our pipeline failed. ):

It's not even our own code. It comes from one of the libraries that we use:

error TS2321: Excessive stack depth comparing types 'ElemMatch<?>' and 'ElemMatch<?>'.
error TS2321: Excessive stack depth comparing types 'InternalQuery<?>' and 'InternalQuery<?>'.
error TS2321: Excessive stack depth comparing types 'SiftQuery<?>' and 'SiftQuery<?>'.

P.S.: Maybe related? #21592

[achansonjr]

After upgrading to TS 3.6.2 got this error from a dependency library Typeorm as well. Reverting back to [email protected] and the issue went away.

node_modules/typeorm/repository/MongoRepository.d.ts:45:5 - error TS2321: Excessive stack depth comparing types '(optionsOrConditions?: string | number | Date | ObjectID | FindOneOptions<Entity> | Partial<Entity> | undefined, maybeOptions?: FindOneOptions<Entity> | undefined) => Promise<...>' and '{ (id?: string | number | Date | ObjectID | undefined, options?: FindOneOptions<Entity> | undefined): Promise<Entity | undefined>; (options?: FindOneOptions<Entity> | undefined): Promise<...>; (conditions?: FindConditions<...> | undefined, options?: FindOneOptions<...> | undefined): Promise<...>; }'.

45     findOne(optionsOrConditions?: string | number | Date | ObjectID | FindOneOptions<Entity> | Partial<Entity>, maybeOptions?: FindOneOptions<Entity>): Promise<Entity | undefined>;

[ghost]

Downgrading to [email protected] resolved the issue for me as well.

[sidewaiise]

Im experiencing this in one of my projects. package.json had ^3.4.3 . Taking away the hat fixed the issue. Using it with loopback 4, so the error was:

error TS2321: Excessive stack depth comparing types 'HasManyRepository<?>' and 'HasManyRepository<?>'.

[lilacdev]

I confirm that [email protected] solves this issue for TypeORM users (through NestJS).

[guillaume-roy]

Like @michaelharrisonroth we've just downgraded to [email protected] to solve the issue.

[olehcambel]

Strange error. For me helped to change version of typescript.
f.e. project without node_modules and build.

1. npm i (with [email protected])
2. npm run build it fails with related error
3. npm i -D [email protected]
4. npm run build it build with success

It works vice versa with no matter what version is it(except 3.6.2)

[perzanko]

Same issue here 😎

[IamFlowZ]

Just had this issue occur for me while trying to build a typeorm project in AWS CodeBuild and locally in ubuntu 18.04:

Versions:
Node: v10.16.3 & v12.6.0
Typescript: 3.6.2
TypeORM: 0.2.16

Console output:

[misterjohannesson]

Chiming in with the same error for new version of typeorm.

Node: v12.6.0
typeorm: v0.2.18
typescript: v3.6.2

Downgrading typescript v.3.5.3
And then using @babel/plugin-proposal-decorators for my needed 3.6 feature has worked for now.

[jeromeSH26]

Same issue here, wondering what is the meaning of such an issue...

[hallya]

same issue here with "typescript": "^4.2.3", node v10.16.0

here error appears on match

export function getCookie(key: string) {
  const matches = document.cookie.match(new RegExp(`(?:^|; )${key}=([^;]*)`));

  if (matches) {
    const [, match] = matches;
    const cookieValue = decodeURIComponent(match);
    return cookieValue;
  }
  return null;
}

EDIT :

fixed with Array.from :

export function getCookie(key: string) {
  const matches = document.cookie.match(new RegExp(`(?:^|; )${key}=([^;]*)`));

  if (matches) {
    const [, match] = Array.from(matches);
    const cookieValue = decodeURIComponent(match);
    return cookieValue;
  }
  return null;
}

[tylim88]

same issue here, v4.7.4

playground

no error if i change the type to V extends unknown[]

[AaravShah042]

Facing the same issue
Excessive stack depth comparing types

[Lyokolux]

I am also facing this issue with Prisma when comparing two arraws with the types such as Prisma.<NameOfTheEntity>CreateInput[].

[oom-]

Same with a custom type I wrote coming from Nuxt type
export type FormNitroResponseType<R extends NitroFetchRequest, Y extends AvailableRouterMethod<R>> = Awaited<ReturnType<typeof $fetch<unknown, R, { method: Y } & NitroFetchOptions<R, Y>>>>;

And appearing randomly. It's not always displayed as an error:
error TS2321: Excessive stack depth comparing types

Would be great to have a --max-depth [number] parameter for compilation no?

Btw I'm running Version 5.8.3
