Could not determine the type for the passed topic
Hi,
I have a node that subscribes to one topic and publishes to another. When I ros2 topic list
both the topic subscribed to and published are listed as expected. When I ros2 topic echo <topic name>
, I get the message Could not determine the type for the passed topic
.
I saw a similar topic at github link in which this error shows up using the Connext DDS implementation, but I'm using the opensplice DDS implementation. Its still listed as an open bug, but wanted to check I'm not missing something (more likely).
Any pointers as to what might be causing this? I have other nodes publishing just fine and can be echo'd.
Sincerely, Paul.
Are these topics using custom or standard message types?
I'm publishing to topic /position/gnss which is simply a NavSatFix message...
Did you figure this out? I am having the same problem now with the /odom topic.
I have same problem with /Image topic.
Hello, @PeteBlackerThe3rd
I'm using custom message like below.
I have encountered this message(Could not determine the type for the passed topic).
Thank you.
