XInfoStreamFull returns nil in Groups whereas there is a group listed

[a-agmon]

I have a stream with a registered consumer group.
I can see these details when I run redis-cli

127.0.0.1:6379> XINFO STREAM GROUPTESTSTREAM-XFI-00573-2023-05-12-1816 FULL

       13) "consumers"
       14) (empty array)

However when I call the function XInfoStreamFull on the same stream through the API then Groups slice is nil

How to reproduce

1. Produce message to stream SX
2. Create consumer group GX to stream SX (I specifically used XGroupCreateMkStream with SX and start 0 client.XGroupCreateMkStream(ctx, streamKey, consumerGroup, "0").Err()
3. call the info full function client.XInfoStreamFull(ctx, streamKey, 0).Result()
   Groups collection returns null

version used

@a-agmon Version of go-redis and redis?

[a-agmon]

Apologies @SoulPancake ,
the versions used are:
Redis 7.0.4 (00000000/0) 64 bit
github.com/redis/go-redis/v9 v9.0.4

Also updated in the issue.
I should also say that by updating the latest versions of both, the problem persists ( there are no groups in the collection which is nil, and also err is Redis.Nil

[SoulPancake]

also err is Redis.Nil

Do you mean client.XGroupCreateMkStream(ctx, streamKey, consumerGroup, "0").Err() returns nil?
Where do you get the error?

[a-agmon]

XInfoStreamFull returns err Redis.Nil
When I examine the data it returns in addition to the err, then I see that all the properties of the stream are there, besides the groups collection.
I will try to create a reproducible script a little bit later on today
