In cases where an exec start failed the exec process will be nil even though the channel to signal that the exec started was closed. Ideally ExecConfig would get a nice refactor to handle this case better (ie. it's not started so don't close that channel). This is a minimal fix to prevent NPE. Luckilly this would only get called by a client and only the http request goroutine gets the panic (http lib recovers the panic).

FWIW; I checked if this was needed for the 23.0 branch, but this looks to have been introduced in 4bafaa0#diff-706db5cf0385b14587b021d64bb7edf3ef1b35cf349e8368b1fdfeeeec573a87 (#43564), which is not part of the 23.0 branch. |
