TypeScript errors

[jelhan]

We are running into type errors with packages from this repository in ember-math-helpers:

../node_modules/.pnpm/@glimmer+manager@0.84.2/node_modules/@glimmer/manager/dist/types/lib/public/modifier.d.ts:45:5 - error TS2416: Property 'getTag' in type 'CustomModifierManager<O, ModifierInstance>' is not assignable to the same property in base type 'InternalModifierManager<CustomModifierState<ModifierInstance>, object>'.
  Type '({ tag }: CustomModifierState<ModifierInstance>) => UpdatableTag' is not assignable to type '(modifier: CustomModifierState<ModifierInstance>) => UpdatableTag | null'.
    Type 'MonomorphicTagBase<MonomorphicTagTypes.Updatable>' is missing the following properties from type 'MonomorphicTagBase<MonomorphicTagTypes.Updatable>': [TYPE], [COMPUTE]

See https://github.com/RobbieTheWagner/ember-math-helpers/pull/1423 and the failing CI pipeline for reproduction.

Relevant dependencies:

• typescript: 5.4.3
• @glimmer/manager: 0.84.2
• @glimmer/validator: 0.84.2

Looks like you have @glimmer/validator 0.44.0 in your deps, which isn't supported :sweat_smile:

you can use pnpm.overrides to set a min version of @glimmer/validator.

can you provide the pnpm why @glimmer/validator output? we should fix whatever is specifying that ancient of a dep

I don't see @glimmer/validator with 0.44.0 in the dependency tree:

$ pnpm why @glimmer/validator

since you have a monorepo, what's the output of pnpm why @glimmer/validator -r?

Thanks a lot for that hint. The test app has pulled in @glimmer/validator with 0.44.0 as transitive dependency of @glimmer/tracking with version 1.1.2.

@glimmer/tracking 1.1.2
└── @glimmer/validator 0.44.0

Enforcing @glimmer/tracking to be ^0.84.3 with PNPM overrides fixed that issue.
