GitHub user Nintorac created a discussion: Presto connector schema issue
Hey :)
I am trying to query my datastream and I get the following
```
presto> select * from pulsar."public/default"."avro-schema-topic" limit 10;
Query 20220823_084000_00014_2f95a failed: Failed to get pulsar topic schema
information for topic persistent://public/default/avro-schema-topic: null
```
my schema is defined like this
```
class SubmissionID(Record):
submission_id = String(required=True)
subreddit = String(required=True)
client = Client('pulsar://localhost:6650')
producer = client.create_producer(
'avro-schema-topic',
schema=AvroSchema(SubmissionID)
)
```
and when I get the schema from the schema endpoint it's fine
```
curl
http://localhost:8080/admin/v2/schemas/public/default/avro-schema-topic/schema
{"version":0,"type":"AVRO","timestamp":0,"data":"{\n \"name\":
\"SubmissionID\",\n \"type\": \"record\",\n \"fields\": [\n {\n \"name\":
\"submission_id\",\n \"type\": \"string\",\n \"default\": null\n },\n {\n
\"name\": \"subreddit\",\n \"type\": \"string\",\n \"default\": null\n
}\n ]\n}","properties":{}}root@pulsar:/pulsar#
```
