A Guide to Handling Errors while Converting a Map to a Promise in Typescript

I am attempting to capture errors if any of the asynchronous code within my map function fails. It seems to enter the error block but does not log anything, as the error variable remains null. Is there an alternative method for handling errors within maps?

await dataService.serviceCall()
      .map(
        async (data: any) => {
                // Do Some Async Stuff
        }, error => {
      console.log(error);
    }
      ).take(1).toPromise()

Answer №1

Have you attempted catching errors after converting to a promise using this approach? If any issues arise during the mapping process, it should log the error to your console.

await dataService.executeCall()
      .map(
        async (data: any) => {
                Add some asynchronous operations here
        }
      ).take(1).toPromise()
       .catch(error => {
        Console.log(error);
      })
