GitHub user dhinesherode91 added a comment to the discussion: Cannot parse 
<null> schema

Thanks for the information.

In my case, in my local I am running a standalone Pulsar and Consumer 
applications are Spring boot application. The above issue is not occurring in 
local.

But in staging and production setups, we are running Pulsar in kubernetes and 
our Consumer spring boot applications are running as Containers. In those 
setups I could see this issue more often and I have to restart my containers to 
make it work.

On debugging we could see like the schema is not available in the consumer 
application pulsar client local cache and due to that on every message receive 
when the pulsar client tries to convert that respective message into respective 
class object by parsing the schema, it throws this 'Cannot parse null schema' 
error.

Something related to having/loading SchemaInfo in the memory. 
It would be great if someone from the team could help us in fixing it.
