After the update to angular-cli beta 24 i started getting this error:

ERROR in ./src/app/shared/services/baseapi.service.ts
Module build failed: Error: /Users/hassan/Code/project/src/app/shared/services/baseapi.service.ts (22,20): Argument of type 'Error' is not assignable to parameter of type 'Scheduler'.

This is the code in context:

	httpGet( URL: string, requestOptions = this.getRequestOptions() ): Observable<any> {
		return this.http.get(URL, requestOptions)
			.retryWhen(error => error.delay(200))
			.timeout(20000, new Error('Request timeout'))   <===== LINE 22
			.map(this.extractData).catch(this.handleError);
	}

If i comment line 22 everything works fine. However, i do want to throw that error of timeout. Any suggestions please?

A timeout always throws a Rx.TimeoutError with the latest rxjs. So the error parameter is unnecessary.

@clydin

@clydin thanks - what if i want to modify what it says ? :)

I'm interested too. I opened a same related question on stackoverflow

http://stackoverflow.com/questions/41320125/how-to-implement-http-post-timeout-wth-last-rjxs-version

@peterpeterparker

@peterpeterparker I can see that you updated your question/answer yesterday on stackoverflow. I am still not sure how can you throw a custom error message with that? (If I dont want to check error message in subscribe method).

@hassanasad

@hassanasad I don't know neither except by checking the error in the error part, but at least, it works again ;)

Sorry but this isn't a CLI problem so I'll have to close it. Stack Overflow is a good place to ask.

@hassanasad

@hassanasad Do you find any solution for this ?

I changed my code as follows (it doesn't necessarily solve the issue but i got over it):

// Get data from server
httpGet( URL: string, requestOptions = this.getRequestOptions() ): Observable<any> {
		
	let tried = 0;
	return this.http.get(URL, requestOptions)
		.retryWhen(error => { 
			// Retry when error.status is NOT 500
			return error
				.switchMap((error) => {
					tried++;
					// If number of tried are over - throw error in each case
					if ( tried >= 4 ) return Observable.throw(error);

					// Retry if error.status is NOT 500 otherwise try again
					return (error.status === 500) ? Observable.throw(error) : Observable.of(error);
				})
				.delay( 500 )  // Number of miliseconds between each retry
				.take( 4 );  // Number of tries
		})
		.timeout( 30000 )   // Total number of miliseconds to throw timeout error
		.map(this.extractData)
		.catch(this.handleError);
}
