According to https://redis.io/commands/ts.madd/#examples, two things:

• you have to repeat the key for each pair of timestamp and value
• it looks like (I have not tested it though) that you have to create the key before using TS.MADD

And last but no least, make sure you don't define (even with an empty value) msg.topic
It creates problems in some cases. Again, not tested with this particular command.
