catchError<TSource, TResult>(handler): OperatorAsyncFunction<TSource, TSource | TResult>
Continues an async-iterable sequence that is terminated by an exception with the async-iterable sequence produced by the handler.
Type Parameters
- TSource
  
  The type of the elements in the source sequence.
- TResult
  
  The type of elements from the handler function.
Parameters
- handler: ((error, signal?) => AsyncIterable<TResult> | Promise<AsyncIterable<TResult>>)
  
  Error handler function, producing another async-iterable sequence.
  - - (error, signal?): AsyncIterable<TResult> | Promise<AsyncIterable<TResult>>
    - Parameters
      
      error: any
      
      Optional signal: AbortSignal
      
      Returns AsyncIterable<TResult> | Promise<AsyncIterable<TResult>>
Returns OperatorAsyncFunction<TSource, TSource | TResult>
