# sequenceTaskResultA

### List.sequenceTaskResultA

Namespace: `FsToolkit.ErrorHandling`

Function Signature:

```
Task<Result<'a, 'b>> list -> Task<Result<'a list, 'b list>>
```

Note that `sequence` is the same as `traverse id`. See also [List.traverseTaskResultA](/fstoolkit-errorhandling/fstoolkit.errorhandling/taskresult/lists/traversetaskresulta.md).

This is applicative, collecting all errors.

This is the same as [sequenceResultA](broken://pages/-LO2tZXFrfCbmLpqbjE1) except that it uses `Task<Result<_,_>>` instead of `Result<_,_>`.
