Binary logit model

I want to estimate a binary logit model with stata, I used this command “logistic seuil1 profession region age statumatri education”, but it is always this window that appears:

outcome does not vary; remember:
0 = negative outcome,
all other nonmissing values = positive outcome
I do not know where is exactly the problem?
please help me

Many thanks to y’all!

This is not a stata support forum! For your problem, check the dependent variable (e.g. plot it). Does it really have negative values (or is already coded with only 1 and -1 as values)?
