I have upgraded my Angular app to version 15 from 14.
After upgrade I am getting following errors
Error: node_modules/preact/src/jsx.d.ts:1078:3 - error TS2552: Cannot find name 'PictureInPictureEvent'. Did you mean 'PictureInPictureEventHandler'?
node_modules/preact/src/jsx.d.ts:1124:3 - error TS2344: Type 'TargetedPictureInPictureEvent<Target>' does not satisfy the constraint 'TargetedEvent<EventTarget, Event>'.
Following are the config details
"compilerOptions": {
"baseUrl": "./",
"outDir": "./dist/out-tsc",
"target": "ES2022",
"downlevelIteration": true,
"declaration": false,
"importHelpers": true,
"lib": [
"ES2022",
"dom"
"module": "esnext",
"moduleResolution": "node",
"sourceMap": true,
"experimentalDecorators": true,

"suppressImplicitAnyIndexErrors": true,
"typeRoots": [
"node_modules/@types"
"watch": false
"exclude": [

"strictInjectionParameters": true
What am I doing wrong here?
You need to use TS 4.9+ w/ Preact v10.15.0. You can upgrade your TS version or downgrade Preact.

This issue is due to a version mismatch of TS and Preact.
After trying to update TS for different versions to check compatibility with Preact I was still not able to solve this.
What solved this issue for me was adding the following statement within "compilerOptions" in tsconfig.json file.
"skipLibCheck": true
