ksqldb: Unhandled exception java.lang.NullPointerException: Cannot invoke "io.vertx.core.http.HttpClientRequest.response(io.vertx.core.Handler)" because "request" is null

[chethan8592]

below is my configuration for ksqldb with akhq:

connections:
development:
properties:
bootstrap.servers: "akhq-kafka_ui.com:443" # Development
security.protocol: "SSL"
ssl.keystore.location: "/app/kafka.keystore.jks" #Need to read from keyvault
ssl.keystore.password: "xyz"
ssl.truststore.location: "/app/kafka.truststore.jks"
ssl.truststore.password: "xyz"
schema-registry:
url: "https://kafka-schemaregistry.com"
properties:
schema.registry.ssl.keystore.location: "/app/schema-registry-0.keystore.jks"
schema.registry.ssl.keystore.password: "xyz"
schema.registry.ssl.truststore.location: "/app/schema-registry.truststore.jks"
schema.registry.ssl.truststore.password: "xyz"
ksqldb:
- name: "ksqldb"
url: "https://kafka-ksqldb.com:8088"
useTLS: true
useAlpn: true
properties:
security.protocol: "SSL"
ssl.keystore.location: "/app/kafka.keystore.jks"
ssl.keystore.password: "xyz"
ssl.truststore.location: "/app/kafka.truststore.jks"
ssl.truststore.password: "xyz"

for above configuration, getting below error:
