Hi, I am a beginner with DeepStream Composer. I am using DeepStream 6.3 and would like to send metadata to Redis, but I have encountered a problem.

Thank you in advance for your help.

Seems the broker server is not reachable. Please refer to Gst-nvmsgbroker — DeepStream 6.3 Release documentation to configure the nvdsmsgbroker.

Have you tried c/c++ deepstream-test4 to send the message before you start with Graph Composer?

I tried with test4, but this error is displayed.
Also, test4 is specific to Kafka, while my requirement is for Redis.

I also tried following your documentation, but a similar error is displayed.

I solved this problem, and I successfully ran the test4 example while saving the results in Redis.
After that, I ran my custom graph, which executed correctly, but the metadata was not saved in Redis. Why?

test 4 :

my custom graph :
