What did you do?
This is part of a bigger application, but here is a repo:
https://go.dev/play/p/mD-R6gerA4c
What did you expect to see?
I expect that the net.OpErr which is returned by net.dialer.DialContext included the wrapped original error, which is a context.Canceled error.
This may be the problematic function. There is also a TODO from @bradfitz

// mapErr maps from the context errors to the historical internal net |
|
// error values. |
|

|
// TODO(bradfitz): get rid of this after adjusting tests and making |
|
// context.DeadlineExceeded implement net.Error? |

func mapErr(err error) error { |
|
switch err { |
|
case context.Canceled: |
|
return errCanceled |
|
case context.DeadlineExceeded: |
|
return errTimeout |
|
default: |
|
return err |

UNEXPECTED:dial tcp: operation was canceled
