[Messenger] messenger:consume offers sync transports to consume from and then immediately throws an exception #51556
Description
Symfony version(s) affected
6.3.3
Description
When running messenger:consume without a transport, it asks to select which transport to consume from.
$ bin/console messenger:consume
Which transports/receivers do you want to consume?
Choose which receivers you want to consume messages from in order of priority.
Hint: to consume from multiple, use a list of their names, e.g. async, default
Select receivers to consume: [async]:
[0] async
[1] default
But, if I select default (which is sync), it immediately throws
In SyncTransport.php line 37:
You cannot receive messages from the Messenger SyncTransport.
making this choice superfluous because the only possible selection is async.
How to reproduce
See above.
Possible Solution
Filter out sync transports and, if only one item remains, consume that immediately.
Additional Context
I guess this could be considered an UX bug.
