I how to fix this error message?
Unable to parse query string for Function QUERY parameter 2:
CANNOT_GROUP_WITHOUT_AGG
I got that error message just from a simple query formula, I already tried to search about it and try with the curly bracket { ... } but it doesn't fixed,
Can anyone help me or ever experienced it?
=QUERY(ANSWER!C:C, "SELECT * GROUP BY C", 0)

If you don't have an agreggation function (such as sum, avg, count in SELECT), there is no use for GROUP BY - you may just delete it.
If you wish to present unique records, use distinct instead.
