Problemperformingfndonusertag

Hello, I have a small clarification question regarding https://github.com/tinode/chat/blob/master/docs/API.md#fnd-and-tags-finding-users-and-topics.

Here is what I am doing:

topic, does a {set topic="fnd"} on public field to

. There is another user in database with

2. Then finally (and unsuccessfully): {get topic="fnd" what="sub"}

I noticed that by setting the

field of the user's

topic to the tag being searched for violates the condition that the

field is a vCard? Currently I am just setting the entire public field to the tag being searched for, no

prefix... Is this where I go wrong?

Here is my server log.. Obviously something is failing with my

, no clue what it could be
