Repro Code
exportdefaultclassPCancelable<T>implementsPromiseLike<T>{privatereadonly_promise:Promise<T>;constructor(){this._promise=newPromise(()=>{});}then<TResult1=T,TResult2=never>(onFulfilled?:|((value:T)=>TResult1|PromiseLike<TResult1>)|undefined|null,onRejected?:|((reason:unknown)=>TResult2|PromiseLike<TResult2>)|undefined|null,):Promise<TResult1|TResult2>{returnthis._promise.then(onFulfilled,onRejected);}catch<TResult>(onRejected?:|((reason:unknown)=>TResult|PromiseLike<TResult>)|undefined|null,):Promise<T|TResult>{returnthis._promise.catch(onRejected);}}
ESLint Config
module.exports={"rules":{"@typescript-eslint/promise-function-async":"error"}}
tsconfig
{"compilerOptions": {"strictNullChecks":true }}Expected Result
exportdefaultclassPCancelable<T>implementsPromiseLike<T>{privatereadonly_promise:Promise<T>;constructor(){this._promise=newPromise(()=>{});}asyncthen<TResult1=T,TResult2=never>(onFulfilled?:|((value:T)=>TResult1|PromiseLike<TResult1>)|undefined|null,onRejected?:|((reason:unknown)=>TResult2|PromiseLike<TResult2>)|undefined|null,):Promise<TResult1|TResult2>{returnthis._promise.then(onFulfilled,onRejected);}asynccatch<TResult>(onRejected?:|((reason:unknown)=>TResult|PromiseLike<TResult>)|undefined|null,):Promise<T|TResult>{returnthis._promise.catch(onRejected);}}
Actual Result
Instead ofasync catch<TResult>(, the fixer producescatch async <TResult>( which is invalid syntax.
