[MDCObjerverFoundation]: Upgrade 14.0.2 to 14.2.2 causes "node_modules/@material/base/observer-foundation.d.ts:25:75 - error TS2344: Type 'Ada

[VashJuan]

Bug report

I'm using pretty basic functions from Material, but after upgrading to 14.2.2 get: Error: node_modules/@material/base/observer-foundation.d.ts:25:75 - error TS2344: Type 'Adapter' does not satisfy the constraint '{}'. 25 export declare class MDCObserverFoundation extends MDCFoundation {

node_modules/@material/base/observer-foundation.d.ts:25:44
25 export declare class MDCObserverFoundation extends MDCFoundation {

This type parameter might need an extends {} constraint.`

Expected Behavior compilation without errors

Your Environment:

Software	Version(s)
Angular: 14.2.2
CDK/Material: 14.2.2
Browser(s): Chrome (latest updates)
Operating System (e.g. Windows, macOS, Ubuntu): Windows 10 (all updates)

Possible solution

Going from: export declare class MDCObserverFoundation<Adapter> extends MDCFoundation<Adapter> { to: export declare class MDCObserverFoundation<Adapter extends {}> extends MDCFoundation<Adapter> { in file node_modules/@material/base/observer-foundation.d.ts:25:75 seems to fix it.

Previously reported as https://github.com/angular/components/issues/25657, but they said it was yours...

Please fix ASAP! This issue is a big blocker for my client.

Update: You can temporarily circumvent this issue by adding "skipLibCheck": true to your tsconfig.json

Any plans to include this simple pull request? Anyone using this code in Typescript needs to redo this fix every time we update Angular. Uggg!

Others should also add comments/requests for this as I suspect the team only looks at issues with recent activity or a number of reports....

I am facing the same issue. Upgrading from Angular 14 to 15, getting Type 'Adapter' does not satisfy the constraint '{}'.
