GitHub user congbobo184 added a comment to the discussion: Cannot parse <null> schema
@robshep Sorry to hear that, AvroSchema has been in the production environment for a long time. It is a stable feature. I think you can use one topic to test and use ```./pulsar-admin schemas get persistent://tenant/namespace/topic --version``` to find out this version of schema in broker or provide a stable way to reproduce for me, I will reproduce it. include. (schema compatibility, all version schema, producer and consumer update order and update schema.) I think this is not a problem that can prevent you from entering the production environment, we can try to solve this problem together. You can ping me in pulsar slack general channel. my clack name is ```CongBo```. Expect you to find me :) GitHub link: https://github.com/apache/pulsar/discussions/18948#discussioncomment-4414965 ---- This is an automatically sent email for dev@pulsar.apache.org.
