"Error 500" in global search

[dabasystem]

When searching, an error 500 appears. I have looked at the error log and this message appears --> "[2018-07-26 07:41:40] Espo.ERROR: Display Error: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'opportunity.assigned_user_id' in 'where clause', Code: 42S22 URL: /api/v1/GlobalSearch?q=CONDAL%20TRADE%20BARCELONA%20SA&max Size=5&offset=0&sortBy=id&asc= [] []"

What can happen? How can I solve it?

A greeting

With the administrator it works correctly. :S

Can't reproduce.

SOLVED! The problem was that the global search engine had many entities. I have left 8 only (since adjustments) and great, it works!

I mention it in case someone is in the same situation.
