Redis [BUG] Getting last item from stream with XREAD + special operator returns error

Describe the bug

from the docs

there is this command that reads last item from all streams

> XREAD STREAM streamA streamB streamC streamD + + + +

but using "STREAM" results in "ERR syntax error". Maybe it was a typo, but using

> XREAD STREAMS streamA streamB streamC streamD + + + +

leads to "ERR Invalid stream ID specified as stream command argument" error.

I have not successfully used the XREAD with + operator as mentioned in the docs yet

To reproduce

call

> XADD streamA * test test
> XREAD STREAMS streamA +

results in "ERR Invalid stream ID specified as stream command argument"

Expected behavior

expects to return last item in stream

Comment From: LiorKogan

This feature was added in Redis 7.4-rc1

• https://github.com/redis/redis/pull/13117 XREAD: new id value + to start reading from the last message

Which version are you using?

Thank you, we will fix the documentation STREAM --> STREAMS.

ok that makes sense, I thought I was already using 7.4. I am still on 7.2. Thanks
